CEL after changing COPs & Plugs

[NavySeabee]

I have a check engine light after changing the spark plugs and COPs. new COPs are Ford replacement and correct plugs were used. Opened coil covers, checked all connections. Anyone else had this issue? Any help would be appreciated.

Get the code first

Yeah, we need the code to be able to help.

Does the car run OK?

Problem solved! Just used my scanner. I had to remove my CAI to get to the COPs. I guess it doesn't hurt to plug the MAF back in. Code cleared & running smooth.

Voltage high on air intake temp sensor = you forgot to plug in MAF, dummy!

Happened to me just five days ago :)
