hi all. need sum help/advice my 1990 320i is constantly blowing whitish grey smoke out a it smells burny/fuely. a its also idleing rough 2.thanks karl

My 320 blows a hell of a lot of white too.....

I disappears really quickly so I just assumed it was the 12mpg being converted to water vapour & Co2........

It does smell a little fuelly though....

I drove it cold up a steep hill yesterday and I felt a bit embarrassed about the amount coming out!!

yep exept mine doesnt seem 2 clear up much 2 b honest. its driveing me mad if i new what it was it wouldnt be 2 bad. : ? think it new engine time but my misses doesnt agree like they ever do

mine struggles to start in the cold, is rough and will stall or back fire under load (above 3kish) until properly warmed up. Been advised to check the blue temp sensor, afm could also be shagged. Check the earth is good so it's getting a proper spark too.

wheres the earth points on them please. a blue temp sensor. thanks

Blue temp sensor is on the front of the 'engine'. Under the throttle body gubbins into the head. There's a brown one in front of it, it's a pig to get at, I gave up in the end, need a double jointed spanner.

cheers il go try that now c what happens

changed temp sensor a it no different. im just scratching my head now a rather fed up.

Just a thought,have you been playing with the AFM?Did you plug the electrical connector back in?I forgot to once, er indoors dragged me from a nice warm bed,saying that my car was ^running funny^I wasent laughing!(With the AFM unpluged,the ECU thinks that the engine is cold and delivers too much liquid gold)

yeh its plugged bk in mate. transplant time i reakon. driveing me mad now.

how did you change the blue temp sender in 48 mins? Yes I know its possible but surely you had to go buy a new one too!?

i already had 1 that i bought for my last bm that i never got round 2 changeing
