TBI idle speed adjustment

[s10maniac24]

my chilton manual says my idle speed can\'t be adjusted since i have a tbi, is this true?

there\'s nothing wrong with it, but last week i broke my idle air speed sensor (overtightened), and until i replaced it, it had a real cool sounding, rough, slow idle (though it would die if i didn\'t jab the throttle now and then) that shook the truck and sounded like it had a big engine. now that it\'s fixed, is there a way to make it sound like that again? (without dying of course)

take the vacuum off the map sensor..or break the new idle controller. Id take a smooth idle over an ole nasty idle anyday.

ive heard there is a hidden screw on the tbi somewhere that is covered,but can be punched out to get to the screw?.i read this somewhere,but im not exactly sure where.it may have been on a 4.3 truck im not sure.

its right where you think it would be...looks like a tiny freeze plug.

to get the that little plug out all you need to do is punch it out right? is it a screw or what kind of screw is it or is it not? bc the 4x4 s10 my wife and i have it needs to bwe turned up also it is doing the same excact thing.

well, that\'s how i found out a v6 could actually sound \"cool\", problem was, it would die very quickly. this was very annoying in traffic coming up to a stoplight, because i would have to slam on my brakes, quick jab the throttle so it wouldn\'t die and then slam on the brakes again. sounded mean though. http://www.s10v8.com/images/smilies/icon_biggrin.gif
