so as i state in the last post, i zeroed out the iac follower tables and it did little to help. it did help in that i can bring the rpm down in gear to about idle and then push in the clutch. with that, it idles normall off the bat. I had another problem tonight... i was driving around the car and showing it to a few friends. we got on a some, but not to redline or anything close. all the sudden the car starts smoking, the idle falls to 500 or so and then dies. (all guages look good). so we start it back up and it fires right up and goes straight to idle. (never did that before). i then drove it to the nearest gas station and took a look. i found nothing that would make smoke like it did. i wasn't even on it when it started smoking. I'm almost positive my brake fluid leaks out when i brake hard or turn hard onto the headers. i was breaking somewhat hard. anyway, the car drove and idled perfect like it should. no high idle problems whatsoever. then i floor it again later that night through 2 gears (taking it to 6k or so... 6800 redline btw) and the damn high idle is back. it's doing the same things i described before. it wanted to idle at 2k right away and took a while to come down. everything is back...high idle starts, coasting, etc. sorry about the reposts, but this thing is killing me. i've tried everything i know of and i can't find a damn thing. keep in mind i actually know what i'm doing when it comes to cars....at least 95% of the time I just can't understand what is going this...? would knock retard or closed loop cause any of this???? mayge enough to send it into limp home mode?? i'm out of idea. thanks.

 

anybody have any ideas?

 

If its idling at 2000rpm, its got to be getting air from somewhere.

Where was the smoke coming from? Engine compartment, exhaust, under the car...etc???? What color was the smoke? What did it smell like?

Why does you brake fluid leak when you use the brakes or corner?

I can't remember what you looked at before..... vacuum to the brake booster? ...... PCV system?

 

I've tried everything possible for vaccum. it just can't be that
usually vaccum leaks make it runs bad in all rpm. occasionally when something happens it will go to normal. then it goes wacky again when you floor it. It has gotten 30% better since i zeroed out the follower tables.... the smoke was coming from my clutch since my friend is a moron and doesn't know how to drive. i just remembered it was my old car that spilled the fluid...bad rubber gasket. btw, i did all the vaccum tests possible and found nothing, although i am stil only making 11inHG or so with this cam. i even did the test around the intake manifold itself. i plugged all vaccum holes in the intake and still the same. since it straightens out, it just leaves me to believe it's not the problem. like i said, there were a few times where it drove completely normal 100%, but then it acted up again.

 

how old is your throttle body? the blades could be sticking on it and causing it to idle high. or the bushings on sides could just be worn out thus sucking air from there.
check this out if you have exhasted all possibilities.

 

i'd like to believe it's that but i had this same TB on the old stock setup and i never had this problem. i took it all apart and cleaned it again to make sure, as well as the IAC. i then replaced the iac...still nothing

 

i'd like it to be tune or computer related...I'd hate to go to speed inc for dyno tuning this friday (I'm already scheduled) and have them tell me it's something else and they can't tune it.
