    Seemingly random, intermittent high idle?

    well this issue seems to have sorted itself out. When i was looking down in the iac passage it seemed fine visually. I sprayed some cleaner on the tip of the pintle and then tapped the throttle on and off so the iac pintle would extend and retract. i figured if there was some residue sitting...

    Seemingly random, intermittent high idle?

    thats good news. Maybe i will put them on the back burner for now. Ive used the grease on every wire/plug ive ever changed also. im probably just experiencing a case of "WebMD effect" thinking everything is gonna go horribly wrong and kill me or something. Today if everything goes well im...

    Seemingly random, intermittent high idle?

    I did monitor the coolant level after the intake gasket job, and it needed to be topped up a few times but its maintaining coolant level now and i feel the air has been worked out but i will keep this in mind

    Seemingly random, intermittent high idle?

    i have done some multimeter testing of the TPS while mounted to the TB and moving the throttle plates manually but this was with a digital HF multi meter, so i might first try with an analog one. I also did test for voltage at the connector with ignition on, and also pulled the TPS and tested...

    Seemingly random, intermittent high idle?

    this is something ive seen a few times posted when people are talking about issues similar to mine, so i will check this out again for sure. When i cleaned the TB, i sprayed it with TB cleaner with it removed from the intake. I sprayed it down good, probably 2 cans of cleaner. Basically...

    Seemingly random, intermittent high idle?

    Firstly, i viewed the threads that came up as suggestions when naming this thread. They did not provide any answers for my issue. Secondly, To avoid a massive wall of TLDR text, my previous post that i edited the title to say *Solved* provides backstory on things ive done prior when solving...

    1994 5.7 TBI installing Harmonic balancer, crankshaft balancer, vibration dampener etc

    When i was doing this balancer job, i did not know there was a seal to replace and i was already in the process of putting the balancer back on when i asked for help determining if i was doing it correct. I had a couple people ask if i replaced the seal. I said no cause it was not leaking...

    * solved * (bad egr) Stinky Exhaust and Struggling to hold idle when warmed up

    this seems to be a very common issue and just last night i decided to test my old ECT sensor using little dishes with diff temps of water in it. I found online a list of the correct OHM readings at various temperatures for this sensor and used it as a guide. I determined that my old ECT was...

    * solved * (bad egr) Stinky Exhaust and Struggling to hold idle when warmed up

    TLDR ==> the EGR was the problem, and this issue is now solved, thanks to everyone on here, and also my father-in-law. That emissions document that was posted here helped a ton, and i appreciate everyones input. somewhat short backstory below. Thanks again everyone! So i have been keeping...

    * solved * (bad egr) Stinky Exhaust and Struggling to hold idle when warmed up

    @scott2093 just downloaded the 3 manuals that were listed for 1994, i will look through them, and also ill check out that one regarding the emissions electrical diagnosis. Thank you for those links.

    * solved * (bad egr) Stinky Exhaust and Struggling to hold idle when warmed up

    No codes. The EGR looked pretty normal when i had it off and the diaphragm felt normal, it was not easy, nor too hard to push. I have also disconnected the vacuum line to the EGR while idling and it doesnt change anything. I dont know how to diagnose it beyond that but im open to ideas. I...

    I'm going to try and find something like this. This picture was great it shows me where to put the tool. I was nervous about using those holes but not anymore. Thanks !
