Hey, I have tried and tried to change my idle because I just bought an 87 rx7 and the car was idling at 3grand at first. However, after I changed the radiator and alternator and belt and crap it dropped to only 2grand. To be honest I'm not sure how they are related to each other because I am new to working on cars and I am doing everything from an rx7 rebuild manual. I tried turning the idle screw all the way down, but it only went to 1.75rpm.... so if anyone can help me I would greatly appreciate it because I dont want my engine to blow because it is pretty good condition and only has 50K on it... which is like new to me.

 

you need to set your tps set screw..look up "tps adjustment 101" in the search....

 

are you letting the car warmup? It will idle high for a few minutes untill car is warm

 

yup that's what i was about to say
