Oxygen sensors are usually located in the exhaust system. Assuming yours has the V6 engine you have 4 fitted. They are labelled in the attached photo.

Sounds like throttle body and/or its components,"IAC motor-IdleAirControl motor, TPS-ThrottlePositionSensor. Throttle body/Carb cleaner and SeaFoam @the brake booster.

have you tried starting in low and shift manually? aw4 transmission , is that all the time 4x4

You are still getting high or low voltage at tps? What is the voltage and do you have a unstable idle? Put you + lead on terminal 3 and - lead on terminal 1 turn ignition on and check voltage to be at approximately 5 volts. You can also back probe with it connected at center wire and ground probe to a good ground at engine. Turn ignition on it should read between 0.20 - 0.90 slowly manually open throttle it should rise all the way to 4.5 voltd at full open. If its bad change tps if no 5.0 volts from pcm on first test check connections at pcm. The center tps connector supply wire comes from pin 22 and connection 3 ( which is 5 volt supply ) comes from pin 6. You should be able to back probe pin 6 turn ignition on and have 5 volts. If not 5 v brain has problem.

Engine mounts do not go bad in five miles. Sounds like you're treating a symptom and not the cause of a more serious issue. Are you sure all cylinders are firing correctly? That the severe knocking is not coming from your engine internals? Have you checked the steel around the engine mounting points for cracks or other damage? And just in case, if the mounts you are using are poly, are you lubing them before installation?

Have the catalytic converter tested at your local Muffler Shop...This should be a free test...A clogged converter can cause all 3 of your problems...Hope this helps.

the firing order should be - 1-6-5-4-3-2 , Front Bank 1-3-5, Rear Bank 2-4-6. Hope this helps.
