Hi every1 can any1 please give me some advice on my car its a 2003 220cdi it drives great until it hits 3000rpm then it just cuts out but it starts again no problem i got the car put on a obd2 machine and it came back saying problem with no4 heater plug but surely the heater plug wouldnt cause the car to cut out ? it doesnt just happen when it is cold

Possible Crankshaft Position Sensor.. The MAF or air flow meter or wouldnt make the engine cut out..but will cause it to run bad..

forgot to mention sitting with the car in neutral the car revs over 4000rpm with no problems

check your fuel pressures, and injector leak off at 3,000.

Nice to see you back Star!

As star, i think a leak of test is the next step
