ranger high idle

[t5cents]

ok so i replaced my iac like a week ago. cleaned my maf. cleaned my tb. and i have reset it multiple times to relearn the idle and it still idles around 1100. my tps screw is all the way unscrewed cause even after i set it up right with a voltage meter and reset it and did the idle relearn steps it then idled at about 1800. i have a restrector plate because when i have the regular gasket on the iac it hangs rpms really bad and when i would go to stop it would rev to live 3000+ and then slowly go back down over the time period of like a minute. if u dont know what a restrictor plate it read these.

if i unplug the iac, it does nothing...also i have a knn oil filter and i read somewhere that they can cause throttle sticking...is this true. my butterfly moves fine and the cable is not hanging up or any thing either.but i have noticed that with the tps screw un screwed the butterfly can get tight and kinda jammed in the tb and the peddle kinda sticks and i have to push it down kinda hard to unstick it and then i can use it normal. (not as bad as this makes it sound)

Check and see if you have a vac hose disconnecting...

you need to tighten that screw just about 1/8 of a turn past the point where it doesn't "stick" the butterfly valve. Ive adjusted the idle screw on my car enough im 99% sure I know what your talking about, and ya its not bad if you don't mind it, but its not neccesary.

Personally I wouldn't bandage a problem by adjusting other things. Sounds like a vacuum leak of some sort or a bad sensor. coolant temp sensor? maybe truck thinks its still cold

dont touch the "idle screw"! its the baseline for 0 mark for your tps, messing w/ it will cause problems.

does this mod/fix whatever you would call it, work for the ranger as well. I see T5cents has done it, has anyone else? my ranger seems to drop to idle slower than most cars ive had.
