Car idles fine (maybe a bit low), but after it warms up the car stalls (or tries to stall) when coming to a stop with the clutch in.

Any ideas on what I should check? A VAFC was installed a week or so ago.

 

maybe you're too rich at idle...what else have you done...what is the VAFC set at?

 

my car does that with toda Bs all the time...

basically with the vafc, you can only adjust fuel every 1000 rpm
so when you are coming to a stop and the rpms are dropping to idle
whatever fuel level you were at, say 2000 rpm will not be adjusted until you hit idle speed and too much fuel is being dumped into the combustion chamber

time to go standalone? then you can adjust fuel delivery every 100 rpm

Which specific setting?

Narrow throttle is all +/- 0 across the board.

 

Try to lean it out at idle and see what happens. I installed Toda 'C's a couple of weeks ago, and I had to play with A/F (Hondata) at idle quite a bit before the car wanted to idle properly. Experiment and see what works.

you have to lean it out at the lower rpms on the narrow throttle setting

i was at -35 @1000 rpm with the Bs

 

also look for wisps of black smoke at idle...good indication of where your A/F is at.

I'm beginning to think the guys that tuned my car in Houston really, really, really sucked.

I'm gald I'm getting it re-tuned on tuesday. I think I'll be pleasantly surprised.

 

please keep us posted

 

My car leaves black sut(sp?) on the ground if it idles for like 5-10minutes. It runs really rich. It needs tuned but i dont have the $$$ yet.
