    help me ID these parts please

    i bought the 12mm IAC and put it in, no real change. FYI what i have figured out is that the 10mm has a single taper and the 12mm has a double taper end if that makes sense. they both measure exactly the same. I'm going to remove it and start the truck with it still hooked up to see if its even...

    you are on the right track, if i put the truck in gear without my foot on the brake and let it take off it doesn't stall hardly at all, its when i hold the brake and the engine has to hold that load that it really stalls. I'm going to look at the 2 different IAC valves after work and see what i...

    help me ID these parts please

    no i haven't, how should i check that, spray something around the edge of the gasket? and would that type of leak change as the engine warms up?

    i also found that BWD has a fairly comprehensive parts catalogue, looked it up in there and called their tech line. was told "measure the bottom" http://ecatalog.smpcorp.com/bwd/#/vehicles/Id/212223

    help me ID these parts please

    thanks for checking for me, well my morning update is disappointing. the throttle kicker seems to be working correctly and didn't effect my problem regardless of how i adjust it. i removed the tps and drilled out the mounting holes to allow for more adjustment and it didn't make any real...

    not yet, too busy with family over the weekend. but I'm off work in a couple of hours and will mess with the truck all evening. going to do some adjusting and testing of the throttle kicker and possibly adjust the tps sensor by reaming out the mounting holes a little. did you get a chance to...

    help me ID these parts please

    when i start it up it idles high and doesn't really seem to level off like my other tbi truck does. over 1000 RPM for the first 30 seconds or so then maybe it idles down just a few hundred RPM's, and when i put it in gear then it just tanks. it just never totally smoothes out the way i feel it...

    one other thing i thought of, when i replaced the IAC a while back i saw there were 2 sizes, 12mm and 10mm. now not knowing which one i had i measured mine best i could with some calipers and ended up going with the 12mm. could i have selected the wrong size, would it even fit in my TB? and if...

    help me ID these parts please

    ok i didn't have much time last night but i did get to look at this for a minute, i put some vacuum on the pod and it retracted fine, getting strong vacuum from throttle body. i removed the solenoid and tested it with 12 volts and i heard it clicking and verified it was working. i did find the...

    help me ID these parts please

    and one more thing, if this thing regulates idle by adding or subtracting air then what does it have an IAC for? or do they just support each other somehow? and is any part of the system adjustable or it either works or it doesnt

    help me ID these parts please

    ok great thanks, that's kinda what i was thinking, i will inspect everything i have and go from there. i found the solenoid at a local parts store if it is bad but i haven't found the diaphragm yet. hopefully they don't actually fail that often. the problem I'm having is every time i start the...

    help me ID these parts please

    I'm needing help with these two parts. I'm tracking down a stalling issue on my 1994 K3500 454 and ive read that a "throttle kicker" device can work in conjunction with the IAC to adjust vacuum under load and that it can be manually adjusted. I'm getting the code 36 which is "throttle kicker...

    Thanks, i stepped up from 225's to 265's with a 2" spacer, it worked out perfectly to me. the spacing, stance and proportions are just what i wanted for the truck. finally looks like a 4x4.
