It could be the starter, they can be affected by heat from being near exhaust components, or it could be the starter solenoid... also bad ignition timing could cause that

    if it is the starter you might consider a starter heat sheld while you have it out...thermotec makes a good affordable one

97 cavalier starts and runs ok from a cold start after a few minutes of warm up it starts to run rough and miss. If i try to drive it it will start out ok but won't shift automaticly but shifts fine m


Sounds like possibly more than on problem, crankshaft position sensor, or ignition module likely on starting prob which maybe affecting shifting due to hard code in ecm, or shift prob could be shift solenoid in valve body of transmission. Both parts readily available from local parts store

Cold starting problem


you could have a couple differnet issues. cold start misfires, an intake air leak, poor compression with engine cold,or a fuel pressure issue with a leaking injector or fuel pressure is bleeding back due to a faulty pressure regulator. my recommendation is to buy a fuel pressure gauge and monitor pressure overnight. you could also pull the fuel rail and see if an injector is leaking at the same time. you can spray the intake system with a highly volitile liquid(with engine running) to see if idle speed changes to check for an air leak

97 M3 chokes on clold start.


The E36 M3 is natorious for having some minor enigine hesitation immediately after a cold start. My car does this for about the first block both in the morning and after work. Its part of the engine management start routine: you will see this more specifically if you just start you car when its cold and let it idle. Initially you'll notice that the idle tone is a bit more rumbly and rough; but after about minute or so you'll notice that pitch changes and smoothes out. I was alarmed about this too, but after some research, I found it was a characteristic of the design. Just take it easy for the first block and you will never notice. Don't ever cold rev your engine. - Hope that helps.

Your fuel injection pressure is probably leaking down causing gasoline to leak into the cylinders and resulting in a hard hot starting condition due to "flooding" of the engine. Try holding the accelerator pedal all the way to the floor of the car like your trying to go maximum speed down the highway and crank the engine for 10 seconds or less at a time. That tells your computer to enter the "clear flood" mode and stop injecting gas into the engine. Ask your repair shop to measure the fuel pressure and see if the pressure is bleeding off too rapidly.
