Engine Surging & Gas Mileage
I have a 89 Suzuki Sidekick with EFI. When I have it in drive or reverse it surges, I have replaced the oxygen senser and the PVC valve. I just overhauled the engine with a NEW head job. Does anyone no what I can try to fix this problem?
Also, What kind of gas mileage should I be getting? I am getting about 20 Miles per Gallon!
