Come on guys please respond to the above. The next morning the idle started out at 1300 and now its at 3200 warm. And my lightning blew a plug and they will not fix itSTR1 said:Ok guys this is hands down the most informative thread I have found on the idle subject. I have spent the last two days reading and trying some of the 2years worth of solutions that are posted. Nothing worked yet.
Here it goes , My first post BTW, 92 5.0 auto indicates 98k maybe 198k I do not know. First thing in the morning it starts fine and idles around 850, then after 2-5 mins it goes to 1300. Temp sensor changed Bypass changed, TP changed, comp changed, cap and rotor. I did the 10 pin last night twice, reset the idle 3 times and adjusted the tp from .54 to .97. When I adj the tp the idle went to 2400and came down slowly. I am driving it with the bypass unplugged it seems to responed better. If the car is running and I unplug or plug the bypass in there is no change.
I can introduce air by cracking the boot at the throttle body and the idle will come down. This is air that the MAF does not see. When I introduce air by operating the bypass manually with my finger the idle goes up, this is air the the MAF sees.
I was headed out today to buy a new MAF sensor mine does not have a gasket between the mounting and the MAF body, should it?
Yesterday I was convinced it was the 10pin. I bent all the females twice but did not clean and regrease because I did not have the dielectric grease. Could I have missed it? I did not think so thats why I did it a second time after no results the first time.
