Several problems fixed several more to go
OK first let me take the time to say thank you for creating this forum and thank you to everyone on here that takes the time to help those of us out that really need it before we just put a stick of dynamite in our gas tanks. Thank you for reading my " Book of problems"
OK now the problems.
I have a 1993 Chevrolet lumina apv 2wd with a 3.8 vin L It started out just as a slight hesitation during acceleration shortly after my wife thought she ran it out of gas (she did not) The gauges fluctuate when the turn signals are used sometimes they just crank up to the maximum they can go to ( ex the car sometimes shows astronomical oil pressure almost like a high voltage surge ). I replaced the plug wires. That worked fine for a while. I get the brake light intermittently comes on when in park with a extremely rough idle and stalling when i step on the brake to put it in reverse when i can get it going it is difficult to keep it going . After several minutes things start to work better but no permanent solution yet.The cel is shooting me the following obd 1 codes 34 and 56
Fix Attempts:
Using a meter through various trouble shooting guides i tested each of the sensors and the power and ground supplied to them on the vehicle i can find. All tested to specs. Tps (part of the plug is broken and stuck down inside the receptacle. can still plug in) Egr(removed and cleaned) Maf (removed and cleaned) Checked all vacuum lines and replaced where needed. (There is what appears to be a vacuum on the back of the engine that has not been plugged into anything since i bought the vehicle it has two connections) Checked Iac i think it is called iac Traced wires and repaired where needed.checked plugs and injectors good. checked brake booster vacuum line no apparent leaks or blockages oh yeah i removed the throttle body and cleaned the carbon out of it and out of the top of the engine . I even took some advice on unplugging various sensors and starting the car then replug and see the difference no changes ( example : i did this with isc rpm increased replaced it rpm normal. tested car battery 12 then with load 13.5 v . I even searched out possible corroded grounds and replaced the ones i did see. please help me. I have no hair left to pull out.
