Hi,
I have a problem with my 1989 BMW 325i(mechanically stock).
Here's how it goes, when I start the car when the engine is cold it will idle fine for 3-4 seconds and then it will jump up and down from 800rpm to 3500rpm. When I accelerate the car will kinda junp around until you hit a higher rpm. It will continue to 'idle where it wants' until I've been driving for 10-15minutes(a fair bit of time after the engine is warm)
I was thinking it has something to do with the cold start valve or something. Or it could be the fuel injector cleaner I put in the tank(it was free and i thought it may help). Also, soon after I put the fuel injector cleaner in the fuel pump broke and ever since then it's been acting up.???
Any suggestions or help is gladly appreciated.
Thanks
