    Vibration?

    Yes, seem to be. With it up in the air all looks good. Somebody installed this motor after 2019 and could never have had it running right with bad fuel pump and several sensors. Motor assembly and install appeared to have been done by someone with good sense. They installed hydraulic roller...

    Vibration?

    Hi Schurkey; My brick tells me no knock counts at idle. Is this a good or bad thing? When ecm wire disconnected timing holds steady on 0. When connected the timing fluctuates 2-4 or so degrees. The truck idles sweet with no pops or stumbling. When I grab a handful of throttle while sitting...

    Cold start problems with 1992 GMC 5.7 liter

    I have tried to find in old discussions anything that applies and can't to this point. Have truck running quite well after a few months of headaches. Suddenly it started running super rough when cold started. I can rev it up for a bit and it straightens out. If I disconnect the wire for...
