Question about 1999 GMC Savana
I can start the van, and it idles fine. When I drive it down the road, it won't accelerate properly. I replaced plugs, which it did need, and checked the wires and cap. The motor acts like it's running out of gas. I want to check the fuel pressure to make sure the motor is getting what it needs. Does anyone know the correct fuel pressure? There appears to be a hook up on the left rear section on the fuel rail when I remove the dog house.
Check the TPS. If you code the ECU there might be a P121 stored in the OBD2 port. If tere is no code the a cloged converter will be your best bet.
