91 dodge stealth idle issue

Asked by GuruTC7RK Jun 27, 2018 at 07:19 PM about the 1991 Dodge Stealth 2 Dr ES Hatchback

Question type: Maintenance & Repair

I have a 1991 dodge stealth ES and it idles fine for a few
minutes right after starting but when it gets warmed up or
something it slowly drops idle until it dies I unplugged the
map sensor it seemed to be working then I unplugged the
tps and that seemed to be working too I have no clue why
it’s not idling

Have you checked the ICS (idle control servo)? Mine was doing the same thing: would start fine, then after a short bit, it would just stall. The ICS controls air to the throttle body by a moving plunger. I actually took mine out and tested the resistances on it, and that was fine, but noticed what looked like perhaps a small gap where air ‘might’ be getting passed (it was darker in one area of the plastic gasket). Having said all that, the part was pretty cheap and the swap was also pretty easy. Good luck!
