My 96 GT has recently been having an issue where, with my foot OFF the gas, it would start to idle high. It does this about 3/4 of the time and it can idle high anywhere between 1200 to 2000 RPM, sometimes fluctuating in between. Sometimes it will go back down to around 800 on its own. Also, sometimes I'm able to flip the throttle and it goes back down.
I've already replaced the IAC. I do have a MAF with the post removed (I have my old one but got this for next to nothing), but don't believe this was happening prior to it.
One thing I've noticed is it has done it more since it has gotten colder. Could it be the temp sensor in the intake tube? Could it be a dirty MAF sensor? The hoses were checked out by a mechanic and looked fine. Any ideas? Thanks.
