Hi all, i have had my e30 325ic for about 2 yrs now. its my summer "beater". I have noticed (since last year), that every morning after i start it up, it idles fine. then i started driving it, 1st to 2nd around 30km/h (2000-3000), it would choke and as if no fuel is going through when i press the pedal. this only happens for that 5-10 seconds everyday (after the first gear shift in the morning), and then it drives fine. then after work when i start the car cold (after 8-9 hours) car starts fine, and NO problem at all ! i have notice this only happens in the morning and i really couldn't figure why. open to any suggestions. thanks guys in advance!

My car is doing the exact same thing! I was about to start this thread. But my car does it for 5 minutes and then finally gets better. And stays fine the rest of the day.

Please watch the video. Car idles fine. But when I open up the throttle it seems like it's ducking site but not getting fuel? Need help. E30 Bmw Problem: http://youtu.be/lMMFNpgotpsComment

If all other sensors are working properly (temp sensors, etc) I would consider cracking open the dme to check for moisture/corrosion. I had a similar problem with my 30 years ago with inconsistent no starts/stalls that ended up being caused by moisture in the dme that caused corrosion that caused problems in certain temp/humidity combinations. It was cured with a clean junkyard dme.
I also had a Chevy Colorado that worked fine unless it was below ~60 degrees and damp out, in which case it would stall every 5 minutes or so (there was even a TSB for the Colorado).
Assuming all other systems are working ok, those weird problems are often due to corrosion/damage to the harness or dme causing inconsistent/out or range readings to the ecu.Comment

Even though my car runs fine after it warms up?Comment

Does it smoke? Because I hear that'll make you choke and cough in the morningComment

Possibly. It was very intermittent with mine. Like I said, it's b something worth checking if everything else tests OK.Originally posted by blizake500 View PostComment

Ok so I start my car and it idles fine. Then I get up to about 2500 3000 rpm and it stutters like I'm not getting fuel or I have a vaccum leak. But when my car warms up its acts perfectComment

That sounds like it could be a vacuum leak. Or a bad coolant temp sender. But probably a vacuum leak.Originally posted by blizake500 View PostComment
