one of the map sensor or vacuum switch.
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.
The fuse probably blew that controls the dashboard lights.
Shift selinoid 30 dollars at auto zone
Bad head gasket or weak fuel/ spark.
Perhaps a vacuum leak or bad vacuum check valve in power brake booster
Almost classic example of fuel filter gone bad.
Hey, I got a 91' firebird 305 tbi that had the same exact problem...it's your speed sensor or O2 sensor....(or both)
most likely one of your two coils are bad
because if you stop immediately then the car will stall.
torque converter is hangin up..
Are you kidding me?
Try changing the pcv valve. Also check for blockage on the tube going to it.
