danutt 4 Report post Posted June 3, 2010 (edited) have checked spark to all cylinders, fuel pump and rail is getting fuel airflow meter is good there was no power getting to the sixth cylinders injector so fixed that and no joy replaced 6 cylinders injector and no joy its a 320i and wont idle, if you release the pedal it just dies suggestions please Edited June 3, 2010 by danutt Quote Share this post Link to post Share on other sites

danutt 4 Report post Posted June 3, 2010 car runs without the o2 sensor connected??faulty or broken o2 sensor? checking for leaks now and no reading from tps and car runs without that connected 2 Quote Share this post Link to post Share on other sites
danutt 4 Report post Posted June 3, 2010 also no change in missing idle when you remove 6th plug lead?? bad lead? Quote Share this post Link to post Share on other sites
danutt 4 Report post Posted June 3, 2010 (edited) after wiggling a few grounds near the battery the idle changes when you pull off 6th plug lead? and after putting it back on if u remove the 5th plug lead it just dies? shouldnt it die if you remove the 6th then aswell? faulty lead? bad earth somewhere? oh and no air leaks no vacuum leaks all fine changed tps to one that had a reading on it where the gurus at?haha Edited June 3, 2010 by danutt Quote Share this post Link to post Share on other sites
pureboiracer 0 Report post Posted June 3, 2010 can you post up a vid of it? does the idle fluctuate or hunt? how does it sound when its running? is there an intermitent miss or a constant miss? double check good spark to all cylinders, also remove leads like you did before to check that its only the 6th cylinder at fault.

pureboiracer 0 Report post Posted June 3, 2010 do a compression test on #6, also inspect the spark plug and compare it to the others and tell us what you find... check your idle control valve.(fl or pfl?) check and recheck for any manifold vacuum leaks. recheck the injector you fitted. recheck for any blocks in the fuel rail or anything. check tappet clearances, try swapping #6 lead and plug with another and see if that makes any difference Quote Share this post Link to post Share on other sites
danutt 4 Report post Posted June 4, 2010 injector is sweet, icv is buggered but runs without it connected, used to run smoothly without it connected found a leak today at the icv and fixed it and the car idled smooth even after a few revs with out the icv connected went for a drive and the missfire was back after 5mins have tried other plug leads etc hard to imagine what could block the fuel rail? this missfire is only at idle, when you plant it it goes like it should but if you drive at low rpms or from pull away it will often jerk cheers Quote Share this post Link to post Share on other sites

*Glenn* 854 Report post Posted June 5, 2010 Try another distributor cap & rotor..... and no I'm not being silly. If you have spark on 5 cylinders & not No6 it either has to be a lead or spark distribution Quote Share this post Link to post Share on other sites
danutt 4 Report post Posted June 6, 2010 checked all the leads and dizzy definitly got spark at all the plugs but and its a bit tricky... there is a timing sensor?attached to the 6th plug lead and sends the pulses to the cpu for timing disonnected the 6th plug completely and ran a different plug with no timing sensor and it ran exactly the same with the missfire this leads me to believe the timing sensor is buggered because when you disonnect the timing sensor from the DME? the car dies so if the timing sensor thingy is bust that could have been the problem from the beginning?

Which timing sensor? The #6 inductive pickup sensor is for the injector firing order. If unplugged they will fire sequentially all at the same time. If plugged in, it uses the #6 spark as a reference to fire injectors alternatively 1,3,5 and 2,4,6 in alternative strokes. Quote Share this post Link to post Share on other sites
danutt 4 Report post Posted June 7, 2010 yip that must be the problem then?? changed dizzy cap and the idle is worse so maybe both are the culprit? cheers Quote Share this post Link to post Share on other sites
