after gettin the cobra i havent been driving the sixxer as much. but to save gas and miles i started driving the v6 to work again (it takes me an hr each way) well i noticed that when i let off the gas to coast it wont deccelerate like it should, and when i push in the clutch pedal the RPM's actually increase about 200-400 more and stay there till i come to a complete stop. the RPM's will sit over 2k and stay there untill i come to a complete stop. the pedal feels normal, and nothings feels wrong as far as the drivetrain.

iac?

[bluestang1724]

but wouldnt that affect the idle while sitting also? bc the rpm's are fine if im sitting still. and wouldnt the iac throw a code?

Yes and no. And no, there won't be any code for the IAC. When the IAC goes bad or gets very dirty, the RPMs get really screwy. Sometimes it will keep the RPMs high enough that the car won't decelerate on it's own, sometimes it will keep the RPM's high at idle (any time the clutch is disengaged and you're not pressing the gas), or sometimes it might have your RPM's drop really low and potentially stall the vehicle. I recommend getting a can of carb/TB cleaner, removing the IAC, and spraying it out really well. I did it a number of times on my V6 before it finally cleared up the problem.

ill try that after work today. it doesnt deccelerate on its own. i have to ride the brake going thru the parking lot

Bumping this for a question. My RPM's don't drop immediately when I press in the clutch (probably takes a good 3-4 seconds for them to go down at all) and after I come to a stop in neutral with my foot off the clutch, my RPMs will drop to ~500 and the car sputters and feels like its going to stall unless I give it gas. I assume it's the IAC, but I think I read somewhere that some you can clean and some you have to replace?
Also, where exactly is the IAC on our cars, I watched a couple vids about replacing them on GT's, it would be about the same place right? (Car is at college, I'm home so I can't check right this second lol)

The IAC is on the upper intake, just past the TB, facing the firewall. Start by cleaning it (you might have to pull it off a few times before it finally runs right). If cleaning it a few times just doesn't do the trick, the IAC might be totally shot and then you would have to replace it.

Okay, thanks for the heads up about maybe needing to do it multiple times

if that's the IAC then what is on the intake just past the MAF facing the fender?

Intake air temperature

mqueen said it was past the TB?

[shipwreck_98]

While you are cleaning the IAC, take a minute and do the same with the MAF and the Throttle body. The Throttle body might have a bit of varnish build up in there, spray some cleaner on a lint free rag and wipe around and inside the plate, that should help out a bit too.
