    Possible short in OBD harness?

    When I plug my scan tools into my truck, doesn't matter which one either the reader can't read the truck or the truck radio goes into a reboot loop, I shot some video so if anyone has any ideas I'm open to it all. I have a USB elm 327 that will connect to the truck but the readings go back and...

    Fouling spark plugs

    Sounds like you might want to have a shop run a diagnostic tool on it while its running and monitor the injector pulse width and sensor signals. Sent from my iPhone using Tapatalk

    Fouling spark plugs

    My first test would be to check the ignition system. My 98 chevy ran like **** because the spark plug wires were all leaking. Smelled rich. Burned the paint off my cherry bombs. Open the hood in the dark and Have someone put it in gear and hold the brake and look for sparks. Check your rotor...

    Fouling spark plugs

    If your thermostat is stuck open running your engine cold it will run rich and fowl your plugs. But if its hard starting after sitting your fuel system is bleeding down. May be time for a new pump/filter, FPR, leaky injectors, all sorts of things. Could also be your ignition coil failing Sent...

    New motor or rebuild?

    Im not sure what gears it has. I bought it for 500$ from a dealership with a completely fucked steering system, besides cyl 3 being 10 psi low and cylinder 8 being 7 psi low it has tons of vacuum leaks and oil leaks and looses coolant. But i think its a pinhole in the rad. Sent from my iPhone...

    New motor or rebuild?

As for the cam im looking for that lopey idle and a bit more torque around 1200 rpm. Its got true dual already. But would nice headers help or stock manifolds work just as good...

    New motor or rebuild?

    Cool. Im just gonna hone the cylinders and do a valve job. Clean it up and put it back together this truck is literally used 90% of the time to pull my buddy brad out of the ditch. The other 10% is hauling a car on a flat bed. I just want it to have enough life to go another 5 years. Sent...
