Having a few problems with my gt again ive recently put another bottom end in as the ringlands went again but ever since ive got a few problems 1. Missfire, replaced the distributor cap and rotor arm as they didnt look great, have looked at all the plugs (not very old but got new ones coming) and gapped them all and have new leads coming as 1 doesnt look great but it is missing so much when driving it wont rev at all, will be checking the timing tomorrow but what else could it be? The plug that goes to the top of the distributor seems abit loose cpuld this be it? Maybe wiring issue? 2. It is mapped on emanage blue but there are lights flashing on the end one says interact i think flashing orange and a green one flashing orange should it be like this? 3. Rev gauge has a mind of its own i could rev the car to say 3000rpm but the rev gauge is just moving all over the place? This car is really annoying me now as it is never working!
