Re: 1997 tahoe, shuddering at highways speeds
ok, so IM driving it this morning, wife wasnt back in my car yet, so Im taking kids to school in her tahoe.
its missing all teh time, barely move out of its own way, even when I mash the gas its not 100% now.
the check engine light came back on for a while, then started flashing then stayed on steady.
I hate this truck.
SO If I goto GM and have them diagnose, I am going to pay $79 for them to tell me its a random multiple cylinder misfire?
How do I fix the fuel delivery problem?
is it the cheap fuel pump? dirt in the poppet valve(s)?
are there any of those pour in the tank cleaners that do any cleaning at all?
