Hello everyone! I am a new member, but have been reading here for a while.
I bought a 2004 GTP a month ago with 99k miles. The day after I bought it the check engine light came on and gave a code for a "knock sensor bank 2 low". I run 93 octane fuel, I replaced plugs and wires, and eventually replaced the knock sensor itself. Still getting the same code.
This is new and not sure if it is related. The car idles perfect and even revs smoothly when parked. When I put it in gear it give it gas, it cuts out or chugs. The plugs and wires are 2 weeks old. The fuel pressure was reading 52 psi, so we replaced the fuel pump assembly and the fuel filter. Nothing changed. If I push the gas to the floor it will accelerate, but it chugs and you can hear predetination. The check engine light will flash if I accelerate moderately.
I have a good mechanic working on it, but there is probably more knowledge here than any 1 mechanic can hope to have. I would appreciate any assistance. Thanks!
