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.
You could have a short from the controlls to the fan
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.
The throtle cable is freezing up. Replace it.
There are more possibilities than the mind can imagine.Take it to a repair shop and have them inspect the underside. It could be the engine mounts, they might need replacing, check them first.
Could be a broken belt in one of your radial tires. Have them "spin balanced" to see it this is the problem.
well all i can say is its a piece of junk and u should give away
I had this problem with my 1994 Bonneville SE. would try checking the transmission fluid level(that was the problem with mine). If the transmission fluid level is where it's supposed to be then it could be that the transmission is going out or you may need to check the torque converter. I think that can also cause the problem.
