Was looking for a bit of advice with my friends Supra. Basically it has just started misfiring. I have gone over the plugs, leads and ignitor and all of these seem fine. The plugs, leads and dizzy cap were all new about 12months ago and all look in good nic still. The car isn't pulling up any error codes nor is it loosing oil or water.
Today i took the plugs out, unpluged all of the leads and put it all back together again and the misfire has gone almost gone away, i think there is a slight one still although its hard to tell with the loud exhaust. The plugs were a little wet, but im asuming this is the misfire that is responsible? Or could the car be over fueling and this be the cause?!
Just looking for some advice please
