hi all, it doesnt happen all the time but wen drivin and i put my foot down in any gear i get a missfire at about 5000 revs, dont think its just down to the wet weather, cud it be spark plugs? sellin car soon so need to sort a few little problems out.

 

Ive got this problem too mate. Just bought a MY95 WRX. Any help would be much appreciated

Thanks

 

come on, some 1 must know.

 

IMO Most likely would be in this order:

1) Plugs
2) Coil packs
3) Knock sensor

Coil packs will be the most expensive.
