Misfire At 3k Bad Fuel?

[Klae01]

Hey guys, just fuelled up this morning (BP 98) from empty and now my car misfires over about 3k. no power above that. Its an r34 gtt. Has anyone had problems with a bad batch of fuel or is it just coincidence that ive done a coil pack or spark plug.

PS, it seems like its not just one cylinder down..

Any help would be appreciated..

Unlikely its fuel otherwise it would prob be running poorly at idle also... Replace your spark plugs and gap them down. Especially if you are running above standard boost.. Do this first because it is most likely to at the least eliminate it as a cause. (i had this problem. Feels like i had a rev-limiter at 3500rpm)

Yeah i changed the plugs. Its helped but theres still a miss.. Guess im putting off forking out for coil packs haha

yeh had same with r33. got worse as week went on. misfire above 4k and from 3k if hard on throttle..remove fuel filter and shook then empty into clean container. yellow jelly like crap came out. pump fuel through line for a sec then new filter. back to normal in a sec. wish i knew where i got fuel from...
