New to forum & need help
Hello Everyone,

I Have A 04 Jeep Grand Cherokee Overland 4.7L H.O & It Has Recently Began Idleing Rough Idleing At 600RPM. Jeep Just Broke 100XXX Mile And Has A New Motor That Was Put In At 92XXX Miles. New Coils, New Plugs, Put In Yesterday And Throttle Positioning Sensor & Idle Air Control Motor Are A Year Old.

I Have Cleaned The Throttle Body With Now Change, And The IAC Had Very Little Build Up On It. I Have Tapped The TPS And Unplugged It With No Change.

I Have Noticed There Are Tune Up Kits With PCV Valves In Them Could That Be A Problem or Possibly A Fuel Filter?

Did you check for fault codes set using the key dance? (ignition off/on 3 times and leave it in on at the 3rd time. Odometer will show any faults or "DONE" when all ok.)

All times are GMT -5. The time now is 07:26 PM.
