new wrx owner. flatspot problem. HELP
first of all hi guys, new car 1st problem...
ive got a 2001 bugeye wrx. and between 3500-4000 then 4500-5000 rpm it hesatates a bit (flatspots)...
i have tried looking this up already and come accross a couple of things
1. change the boost pipe connector... done that.
2. reset ecu... did that aswell.
still no joy. ive had it 2 weeks ish and run it on shell v power, could it be the fuel... i cant see why!
going to do plugs and filter this week...
can anyone help me please???
also i have plugged into a diagnostics and no fault codes.
thanks in advance
