Typical rvr is f**ked again. Running rich in 1 and 2 causing it to misfire under 3k rpm. I've replaced almost everything I can think of and it's still boggling me. Injectors were just serviced 2 weeks ago. Fuel pump and filter new. New leads. Plugs. Swapped coil and ignitor. Swapped ecu. Changed injectors from 1 and 2 to 3 and 4 but problem stays in 1 and 2. Changed fuel reg. Boost solenoid and fuel relay. New loom that looked good when I put it in. Has been running fine for 2 to 3 weeks without me touching anything on it has been progressively worse last 3 days. Any ideas? Need it back on the road asap
