So, my rb20det has a bit of a misfire issue.
What happens is while idling sounds okay however when throttle is applied is begins to misfire, i replaced the iridium plugs today, they were completely black with some bcpr6es-11's.
However the problem is still there when doing the spark plugs i did check all the coil packs to make sure they're sparking and they were, one coil pack had look to have been chewed by mice or something but this coil pack still sent spark.
My next step is to replace the fuel filter and put some injector cleaner in the tank.
and my plugs are gaped at 1.1mm is this correct?
Any other suggestions as to what to look for?
E: should mention that the car is running very rich so its most likely a fuel issue
