My 1999 318i e46 bmw is hunting badly on tick over i have replaced the air breather pipe comin from the rocker box and made no differance
Try disconnecting the air mass meter sensor if it runs better then ur air mass meter has failed had the same problem
I have a 2003 bmw 318i and it is surging at idle. this only happens when the engine is cold.
I ave a bigger problem nw wen i start the car its goin straight upto the redline as if the throttel is stuck but i have da cable off nw so its closed but its still goin to the redkine if i disconect the airbox its sitn at 4rpm nd its runnin very bad
I recently Bought a 318is 1996 E36 the engine is very sluggish, i took it to a mechanic who informs me that the engine had been changed to a 318i engine withh the computer boxes be different?
Have u also changed the plastic valve that that pipe is connected to located underneath 2-3 allen key bolts easy if u take off throttle body and housing to get to it???
I GOT AN 2005 E46 318I AUTO BMW .WHEN ITS COLD IT DRIVES OK AS SOON IT REACH TEMPERATURE THE CAR START JURKING AND THEN NO POWER .IF YOU PUT IT IN NUTRAL THEN IT ALSO BATTLE TO REV .WHAT CAN CORS THAT PROBLEM.
You have a lean fuel mixer after the engine rich worm temperature , during the worm up the computer open the injectors for longer time this will dump more fuel ,and the engine will run rich until he rich worm temperature then the computer will stop damping fuel . To adjust the fuel mixer you need to adjust in the air flow meter .All the best.

I have a bmw E46 which is hunting when left to idle, its fine untill the engine reaches operating temperature. The ECU is showing fault code P0171 is present, which suggests an air leak. Any ideas where from? The diagnostic computer also suggests it could be the MAF sensor however the MAF sensor seems to be operating ok when looking at the live data.
