Any difference in how rough the motor is running depending on engine temp?
Reason I am asking is, at least in my case, my 94 would run just fine until engine temp hit around 190 or so.
At first, I thought it was open loop/closed loop issue. It turned out, at least in some cases, injector would run fine until it heated up at which point it would start to short out internally.
Also, #3 and 4 are not on the same coil. I think #4 and 7 and #3 and 2 are correct pairing for coils.
