As the title says, my 91 318i has a relatively smooth idle from a cold start, but if I start it when the engine's already warm, it's rough to the point where it's stalled a couple of times. If I lay on the accelerator, it hesitates for a few seconds, then finally revs, and once I've reved it up to around 3k, it runs pretty smooth. No problems pulling up to redline in all gears once I've gotten it reved up like that.
Honestly, what this problem feels most like to me is my old motorcycle with carbs instead of fi. Does this sound like an air problem or a fuel problem, or is it impossible to tell without taking things apart? I feel certain that I have some vac leaks, and mess under the intake is on my to do list. But if my injectors or fuel lines need to be messed with, I'd rather know going into it so I can deal with them before putting the intake back together.
What do you guys think? Ideas? Thanks.
