This is a follow up to a set of problems I've been having where my car stalls. I finally now have the pictures to show what my car idles at. Given the situtation,; ie: in park or gear.

I have tried everything short of a tune, the next step, to fix it. I'm just wondering if a tune will fix it or cause more problems. When cold my car idles much higher. When warm it drops way down to this level.

You tach could be wrong.....Mine is not dead on with the ScanGauge!!??:confused:

Is there a problem with stalling??:cool:

I have a used but good IAC valve I can send you to try if you like....if you haven't tried a different one!!

I had my Local Mechanic test mine, and they said it was good. I stall when I have my wheels turned and the car is not moving or not moving much. Happens both in drive and reverse.

that idle speed looks really close to mine..but i have no problems...you say it only happens when you turn the wheel?...the pcm should adjust idle higher when it sees power steering pressure increase..maybe you do have a "lazy" IAC motor..i would swap with known good one and see what happens

I agree. I took mine out for another reason, cleaned it with carb cleaner, and then lubed it, and now the car want to stall sometimes. I shouldn't have frogged with it:shake:

Isn't there is a sensor that sends the signal of ps presure to the PCM, perhaps it is bad.

yes there is a sensor in the p/s line that sends a signal to pcm,most are a on/off type switch,when the pressure crosses a threshold the pcm should increase idle..not sure which kind the MM has but it could be bad
