So Ive has a problem with my car and the way it runs, as it gets up to temperature it goes from running fine to really lumpy and black smoke out the exhaust. I have to rev it a little to keep it from stalling.
today I went to move it and it did it before the oil temps even registered and the water temps had nearly risen.
ive unplugged lambda sensor with no change, replaced blue temperature sensor with no change, the distributor was refurbished not so many miles ago and a new coil fitted. I’m in the process of Replacing the battery earth but could it really be that alone?
how can I check Ecu?
