_Alan_ 6 Report post Posted March 21, 2008 (edited) Hey guys, Was driving my mum's '95 E36 320i tonight.. But as I was leaving my sister's place the thing had touble startng - I turned the key to start the car and the car almost started but I felt the engine vibrating and the revs just jumping around 500-1000.. The red lights pretty much remained on.. I tried another couple of times and the same thing happened, the car just stuttered, engine vibrated and failed to start.. Tried about the 4th/5th time and it started prefectly as if nothing happened.. Car has only done 100,000k's .. I've heard of starters failing on e36's but this seemed more like an air and fuel problem.. ? But I'm really not sure... I was wandering if anyone else has had a problem similar to this, or if anyone can offer me some advice on what to check out .. I might take a look at the air filter .. I believe the engine is an M52B20.. Thanks guys - any help would be much appreciated Alan Edited March 21, 2008 by E30schnitzer Quote Share this post Link to post Share on other sites
3 SERIES 93 Report post Posted March 21, 2008 Hi Alan Welcome to the shuddering e36 club! Mines doing the same thing. I start the car, the revs drop to about 500 the engine shudders and revs increase to 1000 or so before dropping again. I know of other people who have the same problem! I actually spoke to a BMW Tech yesterday about it and from what ive been told its normally the throttle control valve which is under the inlet manafold. Either give it a clean out or replace it. Im going to look at getting mine fixed in the next month or so. In the mean time when you start the car just put you foot on the accelerator a little to stop it dropping to the low revs. Id appreciate others input on this too. Cheers Brett Quote Share this post Link to post Share on other sites

Cheers In the meantime I have left it and for the last couple of days since it happened the car has been starting great.. I imagine it will happen from time to time though.. I will let you know what we end up doing if we decide to check it out anytime soon.. Alan Quote Share this post Link to post Share on other sites
zenetti 0 Report post Posted March 24, 2008 Before you guys go spending hundreds of dollars check the air intake pipe between the intake and the air box. It may have a small split in it which can cause the car to surge exactly as you guys are saying. It has happened to me twice on E30's, and has also happened on an FX-GT. You may have to pull the hose off and check for splits,mine have always split on the corrugations where the bends are, which can be quite hard to find.
