engine is stalling when coming to a stop

Canadian Mustang · 04-24-2006, 09:32 PM

Hey guys, I own a 1991 notchback with a 302, I just finished rebuilding the engine, the bottom end is stock except for new rings and bearings. I put on a set of edelbrock performer heads, e cam and a typhoon upper and lower intake. the timing is set to 10 degrees
and the fule pressure is at 40 psi. The car cruises fine but when I'm
coming to a stop the engine will stall out unless I give it some gas.
This is a 5 speed btw.

Thanks in advance

Start with basics, Vacuum leaks at accessories, intake gaskets, etc.

Then Idle speed motor.

Also you might want to check the ignition contol moduel, that what my prob was.

thanks for the replies guys, there are definitley no vacuum leaks, i removed and cleaned
the iac motor and the egr valve and reset the computer. I'm going to take it for a ride
and see what happens.

did you reset the TPS voltage? Get it as close to 0.95V as you can with the key on engine off
