'88 22re has code 5-1. When engine gets to normal temp very slight sporadic sputter/misfire occurs, also, A/C idle step up doesn't occur. When engine cold no misfire and when A/C on, idle steps up like it is supposed to. Also, when jumper "T" and "E" no decrease in idle. Engine runs strong otherwise. Thanks in advance for any help.

 

TPS out of adjustment. Do a search and you will find how to do it.
