Q: 99 durango 5.9l has started behaving really weird. it starts up more or less fine have to crank it more than usual and will idle fine. when i floor it under load rpms wont go over 2-3k it starts coughing and idles very roughly then stalls but sometimes will recover to smooth idle. i hooked up odb scantool and all sensors seem to be in working order. whenever it starts stalling oxy sensor shows lean mix and ignition advance fluctuates wildly between 10-25 degrees. no error codes. i even reset pcm by disconnecting battery - no joy. im thinking ignition trouble... had all wires distributor cap and coil replaced recently with accel hi-perf components... could it have something to do with this any suggestions welcome!!! peter lean mixture coughing long crank time.... check fuel pressure. glenn beasley chrysler tech .
