DunedinDan 0 Report post Posted August 19, 2013 Cranked the car over this morning and it started as it normally does, i gave the throttle a quick blip to clear it's throat which is when there was a huge crack/bang from the engine bay (sounded left hand side) and the car then promptly died. Tried to restart and it cranks but wont catch (with persuasion and a little gas it will catch then die straight away. ) When I lifted the hood I caught a whiff of 'something' electrical, checked fuses but none appear to be blown. a bit of back ground, the alternator belt squeaks on start up sometimes and the battery light wont turn off until the car is revved a bit. Unsure if this is of relevance, it's really the only thing odd that the car does. Any suggestions would be gratefully received. Quote Share this post Link to post Share on other sites

DunedinDan 0 Report post Posted August 19, 2013 If you need someone to have a look I can always pop around one day before work. That would be awesome. Sometime closer to the end of the week? I only had a short amount of time to look at it this arvo , so tomorrow i'll have a proper look and make sure all the intake lines are still attached/in one piece (am wondering if the bang was a back fire in the intake system. Would definitely help to have someone that knows their way around a BMW though. Quote Share this post Link to post Share on other sites

If i try to apply a bit of gas it stalls straight away. Pulled of the distributor cap and it looked ok to me. Uploaded with ImageShack.us Quote Share this post Link to post Share on other sites

Pulled of the distributor cap and it looked ok to me. Uploaded with ImageShack.us Pulled off the afm today and something was immediately wrong in that the bottom of the afm had seperated from the rest of the apperatus. Ran some sealer around the rim of it all and then put it all back together. Car starts now and will rev up but if left idle will just die. Quote Share this post Link to post Share on other sites

Ran some sealer around the rim of it all and then put it all back together. Car starts now and will rev up but if left idle will just die. The AFM has been damaged by a back fire. It's probably bent the vane causing it to stick. Get a new AFM and then check for the backfire issue. It may have also caused a manifold hose or vacuum hose to blow off as well causing the idle issue Edited September 5, 2013 by *Glenn* Quote Share this post Link to post Share on other sites

Balancing the throttle on 1200rpm the car has developed a miss fire as you have suggested, car is expelling alot of unburnt fuel, at least it certainly smells that way.
