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...
ok that's what i thought, ya i got a 16197427 as well, probably didn't need to though, just another part i threw at it trying to fix this issue. thanks again for all of your help. if this thing keeps acting up it might end up for sale. its a sharp truck i just need perfection in my vehicles lol
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"

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...
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...
thanks for all the ideas, here is a list of everything i have done that may help you.
full tune up (plugs wires cap rotor)
new distributor with ignition control module
set timing10 different times (anywhere from 4 to 10 degrees)
IAC
TPS
MAP
CTS
cleaned and tested EGR with ohmmeter (tested good...
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...
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...
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
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...
thanks that's great info! can you elaborate how they work for me as I'm still figuring them out. hopefully they are contribute to my engine stumbling problems.
