car does seem to be more sluggish when warm. And little louder.

Thanks Jack, I was thinking to start cleaning the throttle body.It wasn't doing it before the fuel pump said good buy. If its air in the fuel lines, how can this be bleed ?

sorry , its BAD WAY DETECTION

Hi , Maybe someone had a similar problem . I had replaced the fuel pump about 3 weeks ago. Car never done this before. When waiting at the lights or just idling the RPM jumps down below 500 and goes up again.This is happening when the engine is warm. When is cold it runs like charm.On some occasions it even stalls. I had checked for vacuum leaks.Nothing.Cleaned the MAF sensor. The same. Fault code that shows is 2789 bad way connection . could be the aftermarket fuel pump? No leaks . checked already . My car is 318ci 2002 conv. Anyone had similar problem?

I've been struggling with this for past 6 months. I had tried cleaning and greesing everything that needs to be greased, gummi pledge on the rubber seals, cleaning with alcohol the guides fo front windows where these meet the roof. Adjusting driver and passenger windows. It's not as noisy as it used to be but it is still noisy, especially in the back.Has someone experience similar problems?
