my mpfi series 1 has developed what i think is a fuel problem... i have just had new plugs new leads new coil new oil and filter and got the tube to the map sensor fixed( it had split)... since i had this done i have done about 350/400 k`s...
the reason i think its a fuel problem is it has an inconsistent "miss fire"... its running much worse then if one cylender wasnt fireing... i have cheaked all the plugs and there all seem to be fine (no shit on them)... it wont idle by it self... it blows black smoke... and with a silght rev increse it blows a lot of black smoke( dosent uselly)... it seems to be over fueling its self...
i was trying to run the fuel tank to as low as posable so i could clean it... im thinking maybe it has sucked up some crap from the tank and blocked an injector... does this sound
possable... if so what would be my best line of attack...
the way it started was... driving along and you go to accelorate and it would nearly stall b4 reving up...
Mine started to blow black smoke just after me and my uncle changed the oil and filter. It never did it till we did the oil change. We changed the oil to a different brand and ratio and it stoped straight away.
I have no idea if your's is doing the same. But may be worth a try.
