Melbr33 Posted January 15, 2014 Share Posted January 15, 2014 So my 1998 r34 25gt n/a started misfiring, the misfire will continue throughout the whole time the engine is on, it doesn't make a difference if it's cold or not. I tried the ecu pin test and got code 55 , 55 is a no malfunction code.. I'm wondering if anyone has had a similar experience with there car and how to fix it? Or where I could start? The cars clock is on 121xxx so i have been thinking it is the coils, but no error popped up on the ecu test.

Got a Pulsar Posted January 15, 2014 Share Posted January 15, 2014 Buy a set of NGK copper plugs and try them. BKR6EYA or BCPR6ES. These will be pregapped to 0.8mm. If they have 11 at the end of the number, they are gapped to 1.1mm. approx $30 for 6. Much cheaper than coils. Start with the cheap things first.
