Sti V2 RA backfiring problem
just wondering if anyone has ecnounter backfiring problems on an Sti V2 RA all stock except for exhaust. boost comes on strong but backfire and hesitant after around 5k rpm
Had the following parts replace n tested to see if faulty even though there is no CEL coming on. All of these parts were replace to test:
- ECU/MAP/MAF/ignitor/boost solenoids/ignition coil/camshaft n crankshaft sensors/throttle body assembly/fuel pumps/sparkplugs
what could be causing the problem? it is not overboosting as we have check thru the boost guage
