    Engine Struggling to Accelerate at WoT

    Hi, this is my first post on this forum; I have a 1994 K2500 with a TBI 350. Before I go down a bunch of useless rabbit trails of part purchases I figured I'd see if anyone has a clue about my issue on here. So fairly recently I started to notice the truck was running... I don't know if I...

    Help: WINALDL Readings & No Fuel Prime & Knocking 350 TBI

    Hey there, I have a 1991 c1500 5.7l 250k miles. Bone stock. I just ran WINALDL to help diagnose my knocking engine. Truck only starts after a long crank once the Oil Pressure Switch kicks on the fuel pump, therefore bypassing the ECM- right? Truck does NOT prime fuel with key on, engine...

    Need help identifying noise. Rod knock ?

    I have this 98 C1500 that knocks, I can hear it more at the botom near the flexplate and the oilpan. It more audible when I start the truck but once it's warmed up you can bearly hear it. Rod knock maybe ? Is it worth fixing this or just find a new engine ? It's got 190k miles.
