Perhaps a vacuum leak or bad vacuum check valve in power brake booster
This was originally my question. It ended up being the fuel pressure regulator.
does my 1996 pontiac ga stall out in park
Could be a vacuum leak
alternator is bad
bad booster pump or air in brake lines
if it is automatic then this would be caused by shift down is not working in transmission
one of the map sensor or vacuum switch.
Alternator fails to supply power.
crankshaft position censor
Hey tom its a 1990 pontiact transport van and it starts out fine and as soon as the vehicle warms up it will stall it will start back up but when you put it in gear from park it stall again until cool?
Yes, a catalytic converter can cause a vehicle to vibrate and stall. It will do this when it gets plugged because it causes the fuel mix to be disturbed.
Does it shake and stall when decellerating or at anytime? because mine seems to do that but its only when decellerating at a stop light or stop sign or whever and it dont always do it.. only after long drives. (1992 Pontiac Sunbird). It might be a bad EGR Valve.
