My car (95 WRX RA) has an annoying miss sometimes as I pull away in 1st gear and also when the car is under full boost. This is intermittent which makes it all the more confusing. The plugs and fuel filter have been changed and I've cleaned out all the pipes with break cleaner but the problem persists. Does anyone have any other ideas as to what may be causing this?

i am having a very simular problem, under boost the check engine light comes on, and there is a misfire due to the ecu.
again it is very intermittant, i have a new set of coil packs, the dealer has recomended i try those as a starting point.
