Having problems with your 1997 GMC Sierra ?
I have a GMC and I have replaced all the sensors
\015 I have a 1997 GMC Sierra K 1500 5.7L and I have replaced the crank shaft positioning sensor, throttle positioning sensor, rotoe, plus, wires and also the ECM, fuel filter air cleaner, ect....it starts and runs but when you push the gas peddle to half or full throttle it bogs down really bad...do you have any idea what the problem might be?\015
You may have a restriction in the exhaust, like a clogged catalytic. Converter. The mass air flow and the fuel pressure were good ideas too. lee
