Car stalls again!

[pirotec354]

Ok so im pretty sure i figured out why the car was running so rich.

The intake tube that paxton supplies with there kit had a few holes in it so there was air coming in after the maf. Fixed that.

Took it for a short drive and the a/f ratio is all good now, no more rich mixture while cruising.

But, the car still stalls after i get on it. As soon as i let off the gas the rpms want to drop completely off.

Does this have something to do with KAM? Ive only driven the car maybe 6 or so miles since ive had it back together. Ive had the battery unhooked several times for over a half an hour.

Any ideas or suggestions would be greatly appreciated. Thanks guys.

Anyone know what vacuum should be at at idle?

typical vacuum on a stock engine should be 17 -22.

looks like i need to be checking for vacuum leaks then. My vacuum sits at about 14 right now at idle.

if it's steady then yes that's most likely the cause. also check your ignition timing and if you changed your cam did you time it?? late cam timing could also cause low steady vacuum.

have you checked your IAC??

yea i degreed my cam in when i put it back in. Im going to double check my ignition timing again. But if your talking voltage at the IAC then no i havent checked that yet, i just gave it a good cleaning

make sure the computer is able to change the speed.

during a KOER test the computer checks for that. do a KOEO test as well.
