hi all, new here and need some help .What it is, is that when i drive my frst normal it runs like crap and seems to missfire through the revs.when im on boost it clears and pulls right up with no problems.the car idles fine but when the fuel pump primes it doesnt shut off. ive changed the green relay on the fuse box and fitted a different edis4 off a xr2i 16v and no change.any help would be great.cheers adam
