Car Stuttering In High Gears
#1
Got a prob with my car already in 4th and 5th when i get to about 4000rpm the car stutters and wont pull smoothly.
Anybody shed any light on what its likely to be ? i replaced the wastegate actuator on a 'friends' advice didnt make any difference so that will be going back tomorow !
Thanks

Sounds like the spark plugs to me. Make sure they are gapped to 0.7mm rather than 1.1mm. I had this problem, regapped the plugs and hey presto the car was smooth again

overboost doesn't cause sturttering, it's more like going through the windscreen.
could be plugs
what boost is it running when it happens? If it doesn't do it in 2nd and 3rd is reaching less boost in these gears?

wow loads of replys
Car is 93 WRX, 1st 2nd and third 'seem' ok (got nothin to compare to) im running it on only optimax at the moment knocklink seems fine with it.
Someone suggested changing the coil packs, as that was a likely cause, sound possible ?
