Please could anyone help solve a misfire problem I have. Its a 95 WRX import running approx 300 bhp. When the engine comes under load ie when the boost goes in it seriously misfires. I have checked and changed all the coil packs but to no avail. Has anyone experience a similar problem ? and if so how was it corrected?.

Thanks

What boost level?
Fuel cut rather than misfire i reckon..

Hi, The boost seems to be unimportant its as soon as it comes under load. I dont think its fuel because it doesnt drop off at a level and stay there like normal fuel problems its like if there is water under the HT leads . I know this not to be the problem as it has coil packs on top the plugs but thats how to best describe it....Thanks

check to see if the vacume pipe has come of the fuel presure regulator,i had the same problem with mine,you will find it close to the turbo on the end of the fuel rail.
