Cold start misfire solved (finally!) - Bimmerforums

Could you explain this a little better , hesitates at tip in after you first start it when warm > hesitates at tip in ???? plus after first you first start it when warm . What's warm ? the engine ? The temperature out side ? Or after you had it running an shut it off an restart the vehicle ? The engine temp. is warm , hot etc.... cooling fans working , vapor lock ?

is the check engine light on? have you ever serviced the injectors? if not try that first because there are many things that give the symptoms you spoke of. but this is the cheapest.

I had this problem also and it turned out to be related to the cold start system. cant remember the part name but it was causing the hesitation problem.

We are having the same problem. We are right now changing the crankshaft position sensor along with the intake and manifold gaskets.

1391 is lose off cranksensor or cam sensor like code 340 i would by a cam sensor for that code.356 sounds like a bad coil on #6 which there are one per cylinder .dont worry about code 432 for now.

Im having the same issue I believe. I have a 94\' Chevy 1500 and when i accelerate it will jerk like the gas has cut out but it wont stall. It just jerks and slows me down. It only seems to do it when going up a hill. I feel like it could be the fuel pump or possibly some intake gaskets?

If it has miss and hesitation only warm not cold you may have a coolant temp sensor problem . but if the service engine soon light is off i would chek ignition system(plugs, wires ,boots).most likely one of the cylinders missfires when hot.

run the fault codes
check for problem ambient temp sensor, baro sensor , maf/vaf sensor problems

You might have computer problems.

Does the check engine light come on when it starts to miss?
