only has about 65,000 miles. I've owned it for last 30,000. Not rode hard, local driver by wife mostly and used for trips occasionally. Floored it a few times getting out of traffic, and let the Hemi sing, but very momentarily done the week prior to problems. Don't know if it matters, but could be relevant. Went to store and upon leaving, it seemed off. Acceleration was weak and felt like it was missing a bit. Slowed down and tried limping home. First light i stopped at, it died once I let off pedal. Would not restart. Noticed if i put pedal to the floor, it would fire off, but running like crap and had to stay on the gas to stop from stalling. will only crank if pedal not applied and can smell gas. Towed to house.
Read codes and had misfire on #8 cylinder and multiple misfires.
- Changed #8 coil, spark plugs and injector to #2 (all separate and checked between). no change and only multiple misfire showing up. Spark plugs on both showed rich
- After above, got code for p0113 for IAT sensor high.
- Changed IAT sensor and air filter no change
- Changed Crankshaft Position Sensor no change
- now it has p0300 multiple misfire, p0175 for bank 2 too rich high permanent codes now
- pulled MAP Sensor and cleaned it, got p0108 sensor high code after. Changed MAP sensor, no change and added code to the permanents
- Pulled O2 sensors on both sides, upstream to see if maybe a clogged Cat. Started a little easier, but no significant change and still stalls
- Verified fuel pressure at 58-60psi and holds down to around 40 over 30 minutes after turning off
- Using Foxwell scan tool live data, show cylinder 8 constantly showing more misfires than the rest
- scan tool shows Bank 2 Sensor 1 .685 voltage, sensor 2 .585 Bank 1Sensor 1 .37, sensor 2 .86 when i keep it running
- scan tool shows fuel system closed loop i believe
- scan tool shows Catalyst temperature bank 2 sensor 1 and bank 1 sensor 1 at 860 Celsius
Really at a loss here. I understand it could be a valve spring or lifter. Im about to pull valve cover on Passenger side and inspect and then crank to watch movement. Then if i see nothing, move to drivers and check. ANy ideas or suggestions?? Could the CAM sensor cause all this? Also, if i pull the throttle body to thoroughly clean it, can you perform a relearn without a scan tool as I do not see that on mine.
