What are some ideas to cure a car from missing idle on a clutch in. Many times when I clutch in while driving, the car will miss idle and I'll have to tap the gas to get it to catch or it will die. It is especially bad when I'm off the gas and slowing down. If I clutch in, it will almost certainly shoot past idle.
I'm not sure if it's a spark or air issue. It would seem throttle follower is the answer but I'm not sure. I havn't yet taken the decay rate down to the lowest value but I do have it pretty low, like .0020, and the IAC still closes too fast for it to catch. I wish there was a way to get the IAC valve to close slower the closer it got to the idle count value. I heard ramping up timing around the idle spark area in the base idle spark tables would help to slow the return to idle but I havn't had much luck with that yet, perhaps I just need to fiddle with it more.
One thing is for sure, I've had nothing but problems messing with throttle cracker. It seems it would help if it didn't cut down to 0 when you push the clutch in. I can't even back out of my driveway with out the car dying several times if I have throttle cracker enabled. I'll be backing up with the clutch in and as soon as I push on the brakes, the idle just free falls to 0. I even put in 8g in the 400rpm column and it did nothing since throttle cracker doesn't work with the clutch in. With throttle cracker disabled, the car backs up with a rock solid idle. I tried uping the throttle cracker values a bit in the 800-2000rpm columns too but it didnt help either with the backing up thing.
Could messing with the time delay on the 5 items under Idle RPM>Adaptive Idle fix this?
What am I missing or what have I done wrong or not messed with enough?
I need a new perspective!
Thanks

P.S. I'd like to solve this without throttle cracker if possible, if it's not, then I guess I'll have to use it somehow!
