I need Help.....
Well after a walbro fp (gss342) install my car has been very problematic. When driving below 4.5-5k rpm the car was normal, but trying to rev above that rpm the engine would start to buck/bog and wouldnt go beyond 5k rpm no matter how much throttle i gave it. The engine would just backfire and buck/bog.
Ive tried to give it new gas, new fuel filter, the old fp. Nothing gets rid of this bucking . Now my car is not driveable. It has left me stranded on 2 occations so i do not trust driving it anywhere. With the fuel controller and fuel relay hooked up (like normal) the car will not start b/c the fuel pump will not pressurzes the system. I had to bypass the relay, and trick the fuel controller to run 100% in order for the car to start, and when it is started at any throttle position the car will buck, which progressively gets worse until the car just straight up stalls. So i thinking the ecu is causing a problem somehow. I swapped by vishnu reflashed ecu with my factory mapped ecu and the problem is still the same.
Can anyone shed some light on my problem? It would be GREATLY be appreciated.
