Having the same problem the other guy described.

Replace the High Side O2 sensor as the heater is faulty and CHECK the loom for broken wires as the Transmission fault is probably part of the speed sensor issue; a broken wire.

worn out piston rings require replacement..

My 97 Accord has this issue and I have to clean the idling valve and fast idling valves.They have dirt.

I think I would have it replaced.

It is possible that the sensor was not bad to begin with. Some times another problem will cause the O2 sensor to show a condition when all it is doing is what it is supposed to and a lot of guys will change it. I ran into this myself. I had a code so I had it read. O2 sensor showed a lean condition so the guy suggested I change it. Except it didn`t say which one and there were 4 of them. Didin`t make much sense to me. Turned out I had a bad lower intake gasket which caused the lean fuel mixture because of the un-metered air. All the sensor did was tell me the truth. It did its job. I know this don`t answer your question but this is where a good mechanic comes in and the sensor is located in the exhaust pipe close to the catalytic converter.

Can't tell you exactly what is wrong but the one thing you said is of concern...Map sensor should not be full of oil. If it is, I'd want to know why. In finding the reason for that, you may also find the reason why you are having a problem.
Jeep uses two kinds of engine crank venting. you either have a pcv valve or an orifice controlled system. If either are obstructed it can overpressure the crankcase and cause all kinds of problems.
Years of experience tells me this isn't something I can guess at and be 100% sure I have the right answer but based on what you said, I'd look there first!

P0137--O2 Sensor Circuit Low Voltage-Bank 1 Sensor 2

P0139--O2 Sensor Circuit Slow Response-Bank 1 Sensor 2

P0152--O2 Sensor Circuit High Voltage-Bank 2 Sensor 1

P0300--Random Multiple Cylinder Misfire


I would suspect that the camshaft position sensor is bad. This is a quote from the tech manual:

The Powertrain Control Module (PCM) uses the camshaft position sensor to manage sequential fuel injection and as part of misfire diagnosis. The PCM constantly monitors the number of pulses on the signal circuit. The PCM compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the PCM receives an incorrect number of pulses, Diagnostic Trouble Codes (DTCs) should be stored in the PCM. Some PCM systems will then default to multi-port or "gang-fire" injector operation. The camshaft position sensor signal is required to sequence the injector operation to the proper cylinder timing. If the camshaft position sensor or circuit is faulty, most engines will start. However, the PCM misfire diagnostic will likely be affected.



The part costs $50.....simple to change. It is NOT the O2 sensors so don't go wasting money on those. They are being affected due to related symptoms....they fault because the problem is happening upstream.

One thing to check is the fuel pressure regulator.
If the diaphram is leaking it will cause gas to be pulled into the vacuum system causing lots of white smoke and extreme rough running.

Sounds like possible block in catalyst or broken up and blocked catalyst or oxygen sensor fault causing fuel/air mixture confusion if you take first o2 sensor out of exhaust manifold/pipe and see if performance back then this will confirm blockage although will be slightly noisy while testing cos sensor removed.

I have the same problem, I replace the O2 sensors and nothing??????? I have no idea what to do to take care of the problem. I have just ordered a new and improved throttle body. according to the Mazda6 forum, the throttle body on the 03 model was junk. I'll keep you posted.

On a side note, I was transferred to Richmond, VA for Columbus, OH about an 8 hour drive. I have driven back and forth about 4 times with the check engine light on and have had no problems. my email is [email protected] if you find a solution please let me know and I will do the same.
