Rich from 3500-5000. SUPER rich, like 2 gallons of gas used in 12 miles. Bucking, jerking and then smooth after 5000. The RPM range of the rich spot can be changed with the tps but not eliminated, it just moves it around. It almost feels like there is a short in something that is shutting off the motor. No error codes. Problem has persisted through switching out tps, throttle bodies, fuel rail, PC2 unplug, spark plugs, internal tank fuel fliter clean. Fuel pressure seems to be a consitent 40 lbs. Its a Mr.Turbo kit. Smothed heads, carillo rods, otherwise stock. Problem seems to be worsening.
I'm out of ideas and so is the mechanic working on it and so is our local Suzuki dealership. I have a replacement ecu on the wasy and will try that. I'll try the cam sensor too but I think I'm heading in a random direction. Maybe as simple as a short in the wire harness? I am the Forest Gump of do it yourself motor repair. I'm praying that one of you has an idea because I'm out of options locally.
Any ideas, even off the wall ones will be greatly, GREATLY appreciated--Jonn
