Engine Performance problem
1997 Dodge Ram V8 Four Wheel Drive Manual 80000 miles
fuel pump, cps, plugs, wires, cap and rotor replaced last summer due to rough running problem and finally would not start. Code showed cps bad and was replaced. Ran fine till about xmas. Parked in garage one day, next day would not start. Tried again a few weeks later, started. Was able to run it enough to get out of garage. Tried to move it two days ago, would start, run for few seconds then die. Start again, same thing, then would not start at all. Wait a couple of hours, did same thing all over.
It starts, sometimes, will runs at high rpm if gas pedal pushed down then dies like out of gas. Can do this a few times, then won't start at all. When started will not run at idle.
i have a obd2allinone tool and some free software to read codes. I am not very proficient with this software although I an a computer expert.
some reads do not make sense. Tp shows @ 13% but does not increase when throttle moved but yet engine revs.
these codes look like they are stored in pcm?
all P. 0174, 1126, 3443, 0116, 0166, 3673, 0134, 3005, 2353, 0127, 3941, 2080. Cannot find explanation for some. Only one seems to make sense P0174, engine lean
thanks for any help
