02 4WD V6 Unlimited 160k Miles I'm so glad I fixed my High Idle problems!!! Now I have a Low idle problem. The High idle problem was resolved by replacing both bank 2 O2 sensors and replacing the cracked Passenger PVC hose to the rear of the engine. I also cleaned the IAC unit. Now I have a Low idle problem. Stalls out at the light or in park sometimes. No error codes at all! Where should I start??
