just curious my idle is a tad lumpy at times... just has the ocasional pop... i have read on other forums that they can pop and most seem to do it.... i have been getting a misfire code now too... this only happened since i took the rocker cover....never had any knock codes or misfires before i wondering if i have disturbed something... but theres always been a slight pop on idle....
things i have done the last few months.. cleaned idle control valve new spark plugs, new cam sensor as i had a code come up for this and a really bad misfire cut out.. this cured that fault, new thermostat had some fluctuation temp gauge issued new thermostat cured that too.... got my doubts about the intake tube bellows things as there as some very small cracks in it that i have sealed.... removed coil pack and all the spark leads as i had to take the rocker cover off... I did this evening swap plug 3 for plug 2 to see if the fault moves... service history shows a new coil pack fitted and can confirm its not a genuine bmw item i did notice when i removed it to take the rocker cover off....
car runs / rives fine but this ocassional pop / misfire is irritating... i can reset the code and drive for about 30 40 miles with no issue then all of a sudden it appears...
any thoughts please...
how good is your idle ?
