Help requested, please...

[jdenning002]

I have been experiencing a few issues with my car recently...

I have an 04 CV with a DOHC MM motor out of my 04 MM, novi 1200 SC kit by DR.

It seems like a lot of the folks here have similar issues, maybe the same problem or maybe not.

Anyway, I am sure that my explanation needs work but here goes:

I seem to feel a bit of a rough idle, almost like a miss...

The car feels like it bogs a bit throught the powerband until I get to higher RPMS... Then it feels fine.

At WOT, I get full boost, 9.5- 10 PSI...

If I take my foot off of the gas, the idle surges and dips a bit and fuel pressure pegs and then dips, usually several times.

The only other symptom I can hear is what sounds like a leak in the header gasket. I have had that issue before, I plan to have them replaced this week. (Could that be all that is causing the problem?)

Also, at about 1/3 throttle from a stop the car seems to shift wierd, kind of early and then the RPMS drop just for a split second before the 2-3 shift.

I have replaced the plugs, all 8 COPS, O2 sensors, belt, tensioner, idler pullies and cleaned the MAF, TB, PCV, airfilter, and IAC.

I'd really apprecaite input, Thanks in advance!

John I wish I could help, but I cant fly out there the car ran perfect when it left here correct, till you took the sc off, and this problem is not sc related, as I have said what I can do is help when you get the car to a sct dealer or some one that knows what they are doing. Any good Mustang shop should be able to figure this out.

What is your manifold vacuum readings at idle in Park and Drive?

Also, I would highly recommend performing a compression test to make sure all the cylinders are up to par and not too much deviation between each cylinder.

John as I understand this all this took place after reinstalling the SC is this correct.

[jdenning002]

I noticed the issues prior to the S/C removal and re-install, I started snooping around and that is when I noticed the S/C was leaking.

[jdenning002]

Maniflod pressures are:

Park: 4.4

Neutral: 4.4

Drive: 4.9

I also noticed that the car almost dies when I start it up, it starts fine and then 2-3 seconds it almost dies, 9/10 times it levels out, 1/10 it does die.

[jdenning002]

Replaced the fuel rail pressure sensor, still not it....

[Pat]

John;

After reading DR's posts there obviously is a lot of "history" that we don't know about but may have a bearing on what we perceive as the problem(s)

If you can give us a short synopsis of what has transpired with the car from the last known good point. Even if it's a while back.

It may be something like vacuum hose configuration or emission control hardware as MM BBk suggested.

I found, after changing my EGR valve (2nd time), that I had a worn thru vacuum hose (underside).

There are many vacuum controlled devices and each may have a discrete vacuum source. You may have to run down each hose from beginning to end. But the correct configuration of the vacuum lines has to be assured first.

That looks like the MAP reading from Scangauge.

If you have a Boost/Vacuum gauge installed, what is the reading from that? I'm more familiar with the reading from the vacuum gauge.

[Dennis Reinhart]

One thing that you can do is data log the car save the file and send it to me, you will need to call me so I can tell you what pids to monitor, the car ran perfect up to this point so for any one to try and figure this out by key board is not possible, any good Ford technician should be able to solve this issue, by just looking ant the pids and common sense, the key is for any one to find a good shop, you can trust and has good technicians, even if the car is SC, but a lot of shops to not want to even lift the hood if they know the car is modified.

[jdenning002]

I can't find a single good shop, the closest dealer is out of buisness and the next closest dealer is crooked. I will try the data-log.

[Pat]

Dennis is right. I was lucky, dealership was misleading, shop I was refered to by technician at Sheriff repair barn were great. Correctly diagonised the problem and proved it. You may have to travel a bit. Good luck.

Update:

Check Engine Light came one today, 3 codes:

P0122- TPS Low input

P0507- Idle Ctrl sys RPM Higher than expected

P0511-...

Any other ideas, is it the TPS sensor that needs to be replaced?

No john please do not start swaping parts use the information you have check the TPS this can be done with a scanner the range 0 to 5v from closed throttle to WOT.

If any wires were extended for the 32v swap, id check all solder connections after mention of those codes.

[jdenning002]

If any wires were extended for the 32v swap, id check all solder connections after mention of those codes.

I believe that there was no wires extended, and the main harness just plugged in to the ecm...

[Dennis Reinhart]

We all are trying to help but there can be information overload, no wires were extended it has the the complete marauder wiring harness, now when this is done three wires, have to be switched out this only effects the AC and transmission, so I feel confident this is not the issue, again this is not rocket science it takes a good Ford technician with a good Ford scanner and all this can be T/S and fixed.

[jdenning002]

Dennis, please let me know which PIDs to data-log and send to you.

[Dennis Reinhart]

You have to call John, I asked you that. You have to have live link 5.0 loaded on the laptop and with the xcal 2 connected then I can tell you what pids to use and even save the pid configuration so it can used over again.

ok, can I call you around 7:30- 8:00 tonight?
(that is 4:30-5pm put here, when I get home from work...)

[jdenning002]

Dennis,

Is the tune the you sent me the exact same as the one on the xcal that will not load?

do you know why it will not load?

I was able to monitor fuel pressure on my scan gauge before, and now cannot, if I go back to the "stock" tune I can read it again...

Is this related?

[jdenning002]

That looks like the MAP reading from Scangauge.

If you have a Boost/Vacuum gauge installed, what is the reading from that? I'm more familiar with the reading from the vacuum gauge.

The reading on the boost/vac gauge reading are:

P-15
N-15
D-17

Ok, good to know. I'm afraid that we might be stepping on somebody's toes so I will take a pass on this. Don't want to overload anymore information.

Since you can't find any good Ford technicians, looks like you're stuck with option 1.

We wish you the best in finding your resolution.

No ones toes that I know of are being stepped on, I can imagine how frustrating this would be for any one of us my self included, having a really nice car but being in a area where there is no expertise.

Look at Pat he had the car at the dealer and they sold him stuff that was not even needed and they totaly missdiagnosed the car. That is what I am trying to point out.

If a decent Ford tech would have used one of many of the state of the art scan tools that all Ford/Lincoln/Mercury dealers have Pats car would have been fixed weeks ago. And not sold a fuel pump and a fuel rail pressure sensor or had his fuel rails removed and his injectors cleaned.

These new scan tools can pin point what cylinder and coil is bad. I have a 03 SVT Focus here right now that is driving me nuts, the poor owner has been ripped off by two shops, so I called a company that specializes in these cars for help, it takes 12 min just to make one change and flash with a Xcal 3 there is no way I can bill the guy for the dyno time I have in this car, but after two days I found the problem.

So I feel for John, the car ran perfect when it left here, he drove it to Maryland and then to California so what is that 4000 miles??? and then these issues cropped up after the SC started leaking oil from the rear seal, he sent it in and Vortech fixed it and he put it back on and then this nightmare started.

So I would monitor short term and long term fuel trims banks 1&2 monitor maf load and counts, monitor TPS, and RPM spark advance, IAT and ECT, you can monitor the IAC as well, save the data, and will see what it shows, but he may have to bite the bullet and drive 4 hours to JBA Racing. I drove 1400 miles from Jacksonville Florida to Cleavland Ohio in the worst storm I had ever seen in my life at night, to meet Jerry and he tuned my Mark 8 after two other so called experts burnt two engines up on the dyno. :shake:

[jdenning002]

Thanks Dennis. I really appreciate it. I know you are busy, and I know you cant diagnose the car from 3000 miles away. It was perfect when it left your shop, I understand that things come up, I am 100% happy with everything you have done for me.

I just checked, JBA is at least 8 hours away in San Diego, I am near San Francisco, if it was 4 I would just make the drive....

I will data-log in the morning and send you the file. -And THANKS again.

[dohc324ci]

JD,

Sorry to hear about your issues.

Try (both SCT dealers):

Forcfedperformance. com out of Sacramento, CA. Owner Keith Fletcher email forcefedperformanc@sbcglobal.n et


Once I get my motor I am having Forcefed do the install along with the blower from DR.


or

TPSperformance.com out of Cambell, CA Owner Mike Mak email mikem@tpsmotorsports.com

Good luck.

[jdenning002]

Update:

Data-logs sent to Dennis,

3 new DTC codes:

P0108- MAP voltage hi input...wtf?

P2195-running lean???
P2197-running lean???

Also, I am getting horrible gas mileage, 175 miles to the last tank of gas... (I usually get 275 or more, mostly hwy miles)

^^^How true^^^^

I visited the service department today and asked to see the service manager, he did not answer the page.

I talked to my service writer and pointed out that they should have found the problem since on the receipt it said the ignition system was checked. Silence.

I asked if he would pass on to the Service Manager to check his diagnostic program and see if they have the proper test equipment and that it's functioning.

I told the service writer that they lost $600 in business because of this. He agreed to both.

On the up side, Silverback has a squeaky clean fuel system.


Dennis;

Would a refresh dyno tune be adviseable at the 80K mark, it's 77K now. It was about 55K when you dyno'd it two years ago.

I could swing by your shop in mid November in conjunction with another trip.

Regards,

(I know, I know, call me)

Thanks, for the info, I spoke to both shops today...

I also spoke to Dennis today, he is realy being a huge help. We are going to try a few things before I have to go to another shop...

I would talk to Dennis first about your new setup and see what he reccomends and what he can so, his s/c kits are really amazing, and priced well.

He has taken care of me 100%.
