I recently purchased a 99 Infiniti G20, and when I bought it, the "service engine soon" light was on. I took it to AutoZone and had them read the codes. The only code was Misfire on #1 cylinder. I changed the plugs (put in NGK Platinum) and plug wires, but the code comes back after every clear.
My gut instinct is to replace the #1 fuel injector.
Before I go after that repair, is there anything else I should be thinking that could cause a misfire?
Thanks,
Steve
