Rough Idle

[96laserRedcobra]

I car keeps idling rough and I cant figure out why I changed my oil, plugs, wires, cleaned my Imcr's and values will I was down there and ran sea foam through it, and just changed my fuel filter. After I changed my fuel filter it almost seemed to idle worst after. Any ideas

clean you IAC. that'll most likely fix it.

Where is it and how do I clean it?

It's in the Intake duct off the same harness at the MAF. Take a que-tip and some cleaner and clean it gently.

dont move the needle inside it!!! i just used carb cleaner on mine and it made it idle a little better but still shaky at times,

no no no...i think you are talking about the maf sensor.
the iac is located up by the throttle body. remove the 2 8mm bolts and unplug the harness. spray the inside with carb. cleaner. cover the hole up and shake it for a few seconds. pour it out and give it a few minutes to dry. reinstall it and yer done.
heres a pic of what it looks like

what needle? are you talking about the maf sensor too? the iac doesn't have a needle in it that i'm aware of.

You mean clean the IAT Sensor...? That's what me and mustangdan429 are talking about.

You think it might be better to just replace it?
