    I owned an ‘84 ‘Vette in college. I took that half flow crossram off that engine and installed a ‘77 L82 aluminum Q jet intake with an 800 cfm Q jet. It’s amazing how much more power that engine made after that.

      Ya, the intake manifold is very restrictive. I was told the intake passages were so small because they were trying to get a lag/dead spot out of the rpm range by increasing the air speed into the cylinders. Thanks for watching!

    nice video, i couldn't find the special screwdriver, so i set it by taking the top off, i found turning the pressure screw backwards to what i expected

      I've looked for that tool as well as the IAC block off tools and cant find either. I guess they stopped making them several years ago. Thanks for watching!

    Great video! I suppose without that tool you have to take it off - adjust - put back on and test till you get what you want.

      Thanks Mike! Unfortunately yes, it will take more time and a little more trial and error without the tool, But at least it came still be done fairly easily.

    Great videos! I will have to suggest getting a microphone to help with the audio on your intro.
    I’m having a no crank no start with my 1986 C4. Seems to be a common problem?

      Have you ruled out open cell in battery, tight power connections, cables in good condition?

      @@micahcastillo9113 Yes I did. I spent a half of a day checking and ohming out the wiring from the ECM to all the different component's. Turned out to be multiple problems with the throttle body's they were put together wrong so it had low fuel pressure. One of the new injectors worked but I don't think it was the correct application for that car causing half the engine to lean out and finally after getting it to run on all 8 cylinders the idle was high it took 6 IAC valves before getting 2 that would work and let it properly idle under 1500RPM. Thanks for watching!

    We used to call it "Cease Fire Injection"

      A lot of people did. I think it was the first big step into electronics and not a lot of people new how to work on them or fix them so they took them off and put carburetors on them. They did the same thing to the C1 and C2 Corvettes with mechanical fuel injection very few understood them so they got switched out to carburetors. Now they are paying a small fortune for those old mechanical injection systems. Thanks for watching!
