    60-65 psi, engine off, ignition on. Running a bit less. Below 40 psi and they won't hardly run above idle.

    Re: 97 Chevy Truck 5.7

    I have a 97 chevy silverado
    97 K1500 with the 5.7L. engine. My engine light is on and the obdII scanner is giving me a DTC 1345. I have replaced my spark plugs / wires, distributer cap and rotor and camshaft sensor. I still have the same DTC 1345. In park at an idle the truck idles good, only when I press the accelerator pedal the motor bogs down. I can drive the truck moderatly, but when I accelerate the rpm increases but nothing happens. Can you please give any insight to what might be wrong????? Thanks.

    Code P1345 means there is a problem with the correlation between the cam position sensor and the crank position sensor. You should hook a scan tool (not a code reader) to the truck and make sure that the engine r.p.m. reading does not fluctuate compared to desired r.p.m.. If the r.p.m. reading does fluctuate, the problem could be a bad crank position sensor (that is the sensor under the crank pulley).

    My 98 2500 was spitting out the same code. It had me baffled for a while, but a freind of mine that has a garage ended up figuring it out. It ended up being the distributor gear. It was worn to the point that the gear looked like razors. Replaced the distributor with one from advance auto and the truck has been running great since.
