Strange PGM-FI relay issue
Hello,
I changed by PGM-FI relay after an occasional crank, no start issue. Now I have a check engine light, which is a 7-4 code when you jump the diagnostic pins, this is apparently a cyl. 4 misfire, I've tried resetting the light and that just results in it coming back, I've also tried resetting the light and putting the old PGM-FI relay back in, I still get the same code. I don't feel a misfire however, It seems to run just fine, no loss in power and it idles smooth as can be.
Any help would be appreciated.
