hi im having a few teething problems with my m52 :(

firstly i was hanging the revs when rev'd and driven, i have since removed the ebay maf i bought and fitted a 325 m50 maf. since then it doesnt hang the revs anymore.

iv now got an occasional missfire at low rpm and it will miss when im stood for a few minute or so and i pull away, sound like a few pops from the manifld too.

it idles fine with the maf on and without, without it misses like hell low rpm.

iv tested the coils when its warm and they are 0.6-0.7 and 0.5 when cold.

its poor on fuel but it wasnt getting upto temp because of the stat which i have now changed, its getting up to 60oc as i have a temp gauge with the sender in the top rad hose.

my std one isnt working for some reason tho

any idea's i was going to get it plugged in but i cant get it done till next friday and iv a spare engine to take stuff from
