Having problems with your 1999 Jeep Grand Cherokee ?

99 Jeep Grand...Idle up and down and now a check engine light

\015 I have a 1999 Jeep Grand Cherokee. Lately the idle has been all over the place especially with the A/C is on. Now the check engine light is on and while you are going down the road the RPMs are going up and down by a few 100 rpms when at a constant speed.\015 Posted / edited by AnonymousUser on : 20-11-2017

Its the TPS
Sounds like an air leak somewhere after the air filter chamber.With engine idling spray some carb cleaner at different areas along the intake hose and the intake manifold,any place air can get in.If rpms change you have found leak.
