There could be several reasons why a 1993 Pontiac Bonneville keeps dying. A couple of reasons could be a dirty air control valve or bad spark plugs.
no, check your fluid levels.
You could have a short from the controlls to the fan
if it is automatic the transmission could be slipping if manual the throttle could be sticking
You could try changing the transmission filter and the fluid.
Could be the fuel pump, fuel pump relay or fuse
could be one of the coil packs went bad
it could be a range of things. it could be overheating, gas gauge is low, or your rpms are running too high.
on a 93 Pontiac Bonneville you would remove the passenger side front tire. there may be a plastic cover that just pulls off. look to your left,back and up a little bit you should see the wires that connect to your cam sensor. theres your cam sensor. 91 Bonneville is probably the same.
could be a bad modulator valve but i would change filter and fluid in transmission first
Could be computer related. But alot of time the shifter Solonide goes on them. Get it checked out for that.
Check the Power Steering Fluid level.
