Recently ive had problems with my b17a stalling out. The car is running well except for when i come to a complete stop after the car is warm. When i do, my vacuum guage goes up to 13-14 in. and my rpms drop low to around 400. I am out of ideas over what could be causing this. Any suggestions? Does this indicate i have a vacuum leak? could it be an injector(s)? Or maybe a problem in the valve train itself? what should i look for? thanks

 

could be any of the things you mentioned. Best thing to do would to take it to a mechanic and get them to do an inspection.

 

my guess is the Fuel Pressure Regulator or something with the hose connected to it, one of those 2 things

 

my fuel pressure is set at a healthy 36psi so i know the problem isnt there. (i have a b&m guage). I am running a fast idle thermo valve on my TB and im wondering if maybe that could be a cause? Help please..

 

Anybody?? what can cause a car to stall?? i know somebody must have had a similar problem here...

 

Also, when im driving the car in gear and let off the gas pedal, my vacuum goes up to a healthy 23in hg. when i come to a complete stop the guage rapidly shoots up to around 13 inches. That leads me to believe that there is a vacuum leak in the system. However, i thought that when u have a vacuum leak, the car would idle much to high and not too low? what is the deaL?
