[quote pid=1251 author=hayesey date=1210332855]what do you mean on start up? How long does it overfuel for? What makes you think it is overfuelling anyway? There are a million and one reasons really, starting with basically any of the engine sensors or damaged wires in the loom, although they normally cause problems all the time.[/quote]
mmm well ive tried a different ecu. it just smells very petrol like on intiial start up and i think thats whats causing my problems on start up with the miss fire. I do have a slight blow in the back box but im gonna get a new one this week so that would make it smell a bit i'd have thought but it wouldnt make it do owt else.
it takes a second or so to start missing so its like an electrical fault, like the ecu is getting a bad reading and adjusting wrong.. im starting to think i may have a damaged wire but im not too sure, just thought i would ask this to get thinking about it again. i tried another fuel pressure regulator too..that made no difference. would a damaged or old CO pot cause grief? its set right but its the only sensor i havent changed.
the car will often stall if started cold and left standing. as the idle eventually drops it'll then drop off and stall. doesnt do this at all after a few mins driving.
