    IAC clicking when diagnostics…

    Ya know, I thought pulling the connection was brilliant. However I see that you’re 100% correct - it reads resistance. It’s not off/on. Let me swap that out - I’ll pick one up today - It’s nuts, I’m telling you. This truck should purr like a kitten - it’s driving me crazy. Any brands...

    IAC clicking when diagnostics…

    I think it does too. When all the stars are aligned, if the truck is operating temp, on restart it’ll idle at 900/1000 then settle down to 700rpm. Maybe my cts is going bad? But that doesn’t give reason for such a rich ‘cold loop’ start up after sitting all night. With no codes. Weird.

    IAC clicking when diagnostics…

    When the truck was at operating temp, I checked the coolant temp sensor - unplugged it - idle went up. But Maybe - just maybe, it’s going bad that’s why it’s inconsistent.

    IAC clicking when diagnostics…

    Thanks guys I like it - I just went out disconnected the positive side of battery. I’m sitting fat and happy on the couch so may leave it that way all night - hope it makes a difference- Today on the ride to the house- it was inconsistent too. Thanks again- I feel good about it.

    IAC clicking when diagnostics…

    Snoots - perfect great instructions on resetting the IAC. Thank you. Yesterday, I ended up swapping the 02 sensor, knock sensor and the IAC. I also set base back timing at 0 degrees - It's still acting funny. - Im going to drive it a few days see if it gets better but, the problem is -...

    Heat/AC Blend Doors

    When I rebuilt my heater box I uesed the billet one — it is worth every dime. If you use the plastic one - it will break again - it always does. - the air never stops blowing. Wait till you replace it, the difference is WOW.

    How do I ground diagnostic terminal (ALDL connector)?

    Awesome- thank you- I found a video and it pretty good. I have history with blowing the computer on an old JEEP. Soooo, I’m a little gun shy.

    IAC clicking when diagnostics…

    Hey all - was resetting base timing and base idle- When I grounded my ‘a’ to ‘b’ at my ALDL- (which sets the IAC correctly, so that I can set idle.) Once I turned key to ‘on’ position (truck not running), I can hear the IAC clicking. I figured it was ‘setting’ - I left the truck in ‘on’...

    Hey all- I was googling incorrectly- I found a video that answered my question. It was, as I thought. I was over thinking it.

    short pin ‘a’ to ‘b’ on ADL???

    How do I short pin ‘a’ to ‘b’ on ADL - with a paper clip or jumper wire? I’m basically just connecting the two?

    Frustrated 87 GMC owner!

    oh and - I was having trouble with my TBI - I ended up swapping to a Holley Replacement 670 cfm TBI 1987-89 GM 5.7L V8 truck Part Number: 510-502-6 The reason I stayed with the TBI vs going to a carb is some history with a different 87 I had. The ECM needs the IAC and TPS and ... to run...

    Guys and Gals - thanks to Turbo Dog and Edward Koleman and a few others - I've got the cluster installed. It's not as user friendly as they market and advertise. but I've learned a lot - some of which was 20/20 hindsight. Yes, I've had some trials and tribulations. And still, actually...

    How do I ground diagnostic terminal (ALDL connector)?

    Well dang. That’s pretty ezpz. For my own serenity, would you know why this would have to be done? I’m not questioning if I should - of course I will. Just wondering why. Understanding may help down the road.

    How do I ground diagnostic terminal (ALDL connector)?

    Hey all - I installed a new HOLLEY tbi on my 878 v10. I need to set the base idle. However reading from the drivability manual: STEP # 3 tells me to 'ground the aldl connector' - and in STEP # 4, it says 'Remove ground from Diagnostic Terminal' *** MINIMUM IDLE SPEED ADJUSTMENT - TBI 220...
