The car seems to stall evry time im about to park and come to a dead slow and stalls out when i back up slow, this happens once out of evey 6 times. any clues?

 

When I back up, first thing, cool overnight AM, my car may stall.
I've done everything under the sun to it. Don't care if it satlls any more. I hit reverse, then pop it into neutral, let it neutral back down slight incline, then pull away forward, with no trouble. I keep my RPMS low first thing, to help fluids warm up, too.
I don't even have the desire to cure that reverse stall.
I want to install the tach guage set up & over head console I've got. MORE FUN!!

 

Try the mass airflow senser. it is manual check the vacum to the deseleration valve, its on the alternator. mine was a mass air flow. but after I fixed that I broke the vacum lines to deseleratin valve. it works with the erg system.
