vacuum woes
 
so my 93 318is has a idle issue. i started the car and took off the oil filler cap with ease. Idle increased and sounded better. I unplugged the vacuum line the run from the valve cover to the throttle body, and also had a slight increase. When I plugged the tb and vc hose in the idle surged and was bouncing for about a minute and same with the oil cap. I tried to pull the oil dipstick, but that mofo is not coming out. I've checked for vacuum issues constanly and repaired them. Still no idle fix. Ideas?

Clean the ICV and throttle body. Did you check the intake boots for cracks. Are the plugs clean and check your coils. You might want to change the fuel filter.

Brand new icv tb clean intake boot 4 months old plugs are clean and no. How would I test it? And the idle it bad when I have the headlights on. But the idle only happens when its warm. And napa is getting me a fuel filter soon along with a heater core.

I'm confused. Do you have the idle issue on a cold start or on a warm start or after car warms up and is running.

Hatterer4 10-03-2012 05:40 PM

Only when the car is warm and is running.

i'm concerned about the change when the lights are on. get your charging system checked out.

^ this, for sure. That's not normal at all.

So do you think maybe battery or alternator? And it does runs little low when I'm driving without lights on. Only when it's warm it runs low and wants to stall

I agree, check the alternator.

I don't wanna guess and spend more money where the shop can test it and tell me what's wrong.
