I have a miss fire in the middle of the rev range, idles fine and will rev out some times, it happens the worst on full throttle when pulling at 2500 -4000rpm any ideas chaps? Cheers
change plugs first see what happens
then maybe try different componenets in the ignition system, maybe ht leads, dizzy possibley coilpacks etc, sure that should fix your problem
New plugs have not arrived yet but, I tried a few things... I put a reducer in the front mount air intake like I used before I had a fcd to stop fuel cut and it solved the missfire! So this must mean it's running too lean so I've adjusted the rrfpr up to 3.5 but it's still doing it? Any ideas now? Cheers!
i had this issue, i had my fpr set at 4 bar in end to stop miss fire. it later turned out to be my FCD that was causing the issue. my car was running lean badly and miss firing.
it may be worth changing ht leads and dizzy cap and rotor arm too coz even if dont solve problem it eliminates a option. there not expensive parts and are also general maintenance to keep car runnin well
whats ur setup mate? ie what boost/mods are u running?
as mentioned above check the ignition system, if that checks out fine it could be a setup problem.
kon
Was itthe fcd was nackered or loose wires? Will check over them now!
i had a hks FCD. i had it on too high a setting and caused it really lean. im not clued up on the JAM ones tho. maybe if it get wired in wrong it could have same effect? worth a check. try disconnecting the FCD and see if the problem goes away. thats how i figured out it was mine
