'''Datsun300:''' <small>(2018-07-31 22:25:52)</small>

So I have a 1984 Nissan 300zx ae auto and itâs got a very weird problem going on. last year I replaced the spark plug wires and I did the order wrong and I fixed it but I still had a misfire which I then found out a fuel injector wire broke. Well those wires ended up touching and Iâve had a lot of problems since then like if I floor it the engine like cuts out but if I ease into the load I can go to about 2200rpms, itâs a pain to start in the cold, it wonât idle very good like 6-500 rpms till dies, once warm hard to start because it misfires and back fires. Now weird thing is a while ago the alt overcharged to like 18volts and the car still started like crap but would run good as long as it was overcharged.

"about 2200rpms" sound like limp home mode

See I thought so but if you continue to ease in itâll go to about 2700
