Ive been searching around and cant seem to find a reason for my car throwing the following errors -
P0302,0303 and 0304 - All missfiring cylinders. The car runs ok, seems to have the odd off day but keeps throwing those errors. I have changed the plugs / serviced (only thing not changed was the fuel filter), changed all the coilpacks, reset the ecu, running on 99RON petrol but still the same.
Im getting circa 280 miles to a full tank.
Im kinda stumped! cam sensor? fueling? Its not throwing any errors for that, Ive run new earth cables to the block, head and chassis.
This is on a 2003 Bugeye WRX, only mod is a decat downpipe and thats about it for engine mods.
Hope someone can help
