HELP: 1st gear + clutch + brake = stalling out

[Brent]

There is alot more to adjusting the idle on the throttle body aside from the idle adjustment screw. There are actually a couple of "idle adjustment screws". Also take into account that your TPS might be out of adjustment, butterfly inside throttle body may be sticking etc... which will all give you issues with your idle.

Also, even though you have a street port, the normal vacuum numbers are based off the FD idling at 750rpm's. So having 12 at 1000 seems on the low side to me.

The dashpot is what allows the plates to ease back and maintain the idle when your RPM's would normally drop drastically(ie pulling in the clutch). If your compression turns out to be good, I would guess your dash pot is seized. There are some settings on the PFC that can band aide the problem until you can get another dash pot. If it turns out to be that, let me know and I'll let you know what settings.

Hope compressions tests out strong today.
