Hey guys, i'm having a very hard time with an arcing issue that started after i changed the coils due to check engine light misfire code.
A brief history: This is my first DSM i just purchased it a few months back it's a '98 GSX. It has had an auto swap and appears to still have the 7 bolt engine there's an aftermarket alarm/keyless entry just to be thorough i don't think this matters but ya never know.
The car ran fine at first aside from the check engine light. i started by doing maintenance (simple stuff like, oil, suspension, and ignition).
after the new coils and wires went on i experienced arcing so bad the car would not idle. i could get it to run on 2 cylinders shortly.
What i have done: started with possible bad parts that i got for replacements so i installed the old setup. same issue. also replaced power transistor, cam angle sensor, multiple wires and plugs (yes, NGK) (plugs have been gaped to multiple widths from .30 - .22) even a new ECU. the issue remained so i thought to try to eliminate some variables. ( i understand what follows is not the ideal setup for ignition the purpose was troubleshooting.) i converted to COP to remove the coils as a variable.
I have the car running now at operating temp however the arcing is present at startup and will cause massive loss of power and will run on 2 cylinders only in some instances.
The really annoying part here is i can clearly hear the spark arcing however cannot locate it. there's no visible signs of arc and the boots do not show signs of arcing. the best i can say it's coming from the #4 cylinder area behind the intake manifold?? no idea.
sorry if this is a bit long i am out of ideas and have tried everything i know to do for this problem. anything to get me in the right direction wold be very helpful.
