    350 gets close to stalling when stopping

    I changed the fuel filter on my early 94 when I got it running with the fuel pump sending unit assembly, and ignition coil,then replaced the rusted distributor.. but after all these issues when the throttle body comes off to put a better one back on it that I know is off a 350, I am changing the...

    Diagnosing Rough Idle Hell

    I've actually experienced that before tbi vehicles I had a car that I thought would keep losing power to the electronic choke it would start up after being a throttle singing nightmare when cold, start to kick on high idle, about the time it would normally come down off high idle by touching the...

    Diagnosing Rough Idle Hell

    I usually use pb blaster,or brake kleen flammable brake parts cleaner because that's what I have on hand, already used up the tbi cleaner I had when I was cleaning the iac valve and rebuilding the fuel pressure regulator. And that got me thinking about my earlier statement if this turns out to...

    Diagnosing Rough Idle Hell

    I haven't thrown anything away that I have taken off this truck, except for the idle air control valve I cleaned while my new ac delco unit came in, I just wanted to see how well I could clean it and I gave to a buddy of mine for his truck that ran fine when driving but it's idle was allover the...

    Loopy idle

    So I don't know if the guage reads fairly close or not,I like the guages in this truck but I'll probably do the same thing as I did with the 86 Chevy k20 I traded for this truck it had a sunpro water temp 260' sweep mechanical 2 5/16 guage now I trusted. I didn't worry about having a brand new...

    Loopy idle

    Yes I just mentioned I haven't messed with the one in head til this truck runs well enough to see if it works or not I changed the one by the intake manifold thermostat housing because it was corroded and that is the feedback to the ecm

    Puzzling truck

    True I need to look at it again if I remember correctly the injection pod connector that was bare wires was on the passenger side I would almost bet that is the side with the 305 5279 fuel injector If so I should have paid more attention although I am sure I still would have to replace quite a...

    Loopy idle

    The sensor in the head doesn't look like it has ever been touched, and I bought the coil and the ect by the thermostat because there's a O'Reilly's near where my son goes to school and so that's where I went..

    TBI rebuild

    Yeah that's what I'm thinking well kinda remember that is supposed to be a good useable tbi from a 88 Chevy with a 350, with everything else I have found I'm guessing it either came from the junkyard or bought from eBay and since it had a no name TPS sensor and a half hacked together harness a...
