I have a '95 k2500 with a '78 model 350 installed. My truck will crank fine and drives ok-ish. (Tends to bog a little in bottom end causing excess gas to be used.) But anyways, my truck will crank just fine and I will accelerate to leave my driveway, and it will go as planned, and then it stalls suddenly and i can feel tension in the gas pedal drop. I can hear a pop/thud on the other side of the firewall (almost like it backfires) and just as quick as it stalls, it picks up again and drives just as usual. (Happens within seconds) The man i bought the truck from disconnected the service engine light in dash due to the truck having no 02 sensors (causing the light to stay on), so I have no clue as to if it is throwing a code or not. Truck used to run like a champ before this started happening. Ive replaced: Plugs/wires, coil,distributor,EGR valve and EGR solenoid, MAP sensor, TPS sensor, IAC sensor, Injectors, rebuilt the TBI and replaced gaskets, Intake gasket, Timing chain (due to a skipped tooth), Fuel Pump, fuel pump relay, both temp sensors (one in head and one by thermostat), and i believe thats all. Im at a loss here. Checked for vacuum leaks and can't find anything. Please Help!
this happen almost every time i take off driving and if am doing 40 MHP i let go the go pedal stays at the same speed once i touch the brake pedal the rpms will drop idle, any help will be appreciated
I recently replaced the Distributor, the cap, the rotor, and the cam sensor in my truck and I started it up then it started throwing a code for the cam sensor so I took the new cam sensor out and put the old one in but its still throwing the code does anyone know what might cause this?
when the transmission fluid has time to get warm after 5 to 8 miles driving and you stop at a traffic light or something,it shifts great and strong no slipping but want shift to overdrive.
any suggestions to why it wont fire, it turns over with a new battery!
On the actuator moved to same position as old one and did not move again when I moved control .and the other actuator want move either .can it be control panel
Automatically when the switch was in the off position. I changed out the wiper motor control board but had no luck . The bed is off of the truck and the rear tail light harness is not hooked up. Could the tail light harness not being hooked up cause the windshield wipers to automatically turn on (high speed)when I start the truck? Im currently doing body work to the bed and thats why it is off of the truck. Just hoping for a quick fix.
Truck has 320000 miles. All new up front need shop to do this. I hate the smell of rear differential gear oil and wont go near it. Otberwise every thing else new on the truck inluding engine and 4l80E trans rebuild. Call me. Ill come to you.
