My son purchased a 2000 Tracker 2.0l 4x4. Its been running fine. Started it yesterday morning & it was running well. Left it for awhile to warm up & when he came back it was running very rough. Brought it to me & the catalytic converter was smoking when he arrived. Engine sounds like it's dropping one cylinder and when in gear at idle runs extremely rough, visibly rocking & bouncing. Oil level etc is fine. Friend with a code reader pulled a code P0335 crankshaft position sensor A circut. Does that make sense with these symptoms?

It does not. The crank sensor is only used to detect engine misfires. It does not affect engine performance.

Thank you sir!
