As title says im having a periodical issue with the car hesitating (feels like fuel surges) and occasional misfire on cold idle, doesnt happen all the time only occasional, when it happens the revs bounce about at idle and before the maf was cleaner there was some black smoke coming from exhaust when the problem would happen.
ive changed alot of stuff of the car to try and solve the problem including plugs, leads, dizzy, rotor, fuel filter, fuel pump, had it in having the fuel pump fitted and fueling checked and he said all the fuel pressure, afr's etc are fine, he also cleaned the maf but said it was running a little lean so replace the maf.
I replaced the maf and it didnt cure the problem, i actually tried 3 different mafs and no cure to the problem so it made me think that this is not the issue.
I would like to try and re-earth the maf but im really not sure how to do this and im not too car savvy but i dont know if this will fix anything.
Anyone have any other advice on what to check?
Thanks in advance
