Death @ Idle

[iambennett]

I am currently having an issue @ idle. It seems to be happening at random but I have only noticed it since the temperature has dropped lately (if thats what you can call it in AZ).

It seems to be when I just previously had the throttle wide open and I press the clutch in to drift to a stop light or something.

All that happens is the car falls on its face and just dies. If it doesnt completely die I have noticed the idle will stumble a lot and lately it has been stumbling more sitting at a stop then it ever has.

The car will start right back up no problem. Any ideas? ICV, vaccuum lines, etc.?

Def check icv clean it out its in btwn engine and firewall in case you didn't know also check mess under the intake for broken loose hoses etc vacuum leaks

Does the car idle okay otherwise? If it only happens after full throttle runs, there is a chance that you have a cracked hose or something and the rocking motion of the engine under hard use causes the hole to open up enough to make the engine die. this is a little unlikely though. I guess there is a chance that your AFM is jamming open, and thus won't read the air coming into the engine. Otherwise, the only thing that would really cause that is bad programming of the ECU... If you coast down in gear, and then put in the clutch around 1500-2k revs does it still die?

Check fuel pump too. Read in a post somewhere that a guys fuel pump would die when he went over bumps.
