Ok. So my 95gsx has a 6bolt swap in it. It runs fine until it's warmed up. When it gets to its normal running temperature, it starts to misfire. any ideas/suggestions as to what it might be?
 
When you do a 6-bolt swap on a 95-96 with the CAS pick up on the intake cam gear you'll get a random misfire code. Why? Because the 95-96 ECU will receive a different reading from the 1g CAS.

Easiest thing you can do is buy ECMLink and you can disable the portion of the ECU that detects random misfire.

Since you're in New York at a lower altitude you can try this if you're good with wiring.

You can put a resistor knob on the baro wire to the ECU to fool the ECU into not reading for random misfire.

However most people i know have not been able to make this work. Then again the altitude I'm at makes it harder.

Good luck!
 
I'll try that....as you can probably tell im kinda new to the game...thanks for your suggestions!
