Question about 1997 Pontiac Bonneville
My 97 Bonneville starts and runs great until the engine gets 190-200 degrees. Then it studders, lack of any power and will stop running. it will start when it stes for a couple hours and cools. Replaced almost all sensors including the ignition module. Help!
Hello. It seems either your water temperature sender is malfunctioning or your ignition module is overheating.

Yes I know, but If you hold the accelerator pedal to the floor on a fuel injected car, the Throttle position sensor will tell the computer to enter clear flood mode. Then the computer will shut off the fuel injectors while you have the pedal to the floor. If it is flooded, you should be able to get it started in clear flood.

This car uses a key with a transponder chip in it. The ignition reads the value of the chip thru 2 small contacts just inside the entrance of the keyhole. These contacts are known to get dirty, wear out, or become totally disconnected from the wire they are hooked to. Use electrical cleaner in the lock cylider and run the key in and out a few times to clean the lock. This is your temporary fix. The next item you may want to try ,is having another chip key made. If this doesn't work, then you will need to replace the ignition cylinder. You can try "Plastichead Keys" for these parts. They can be reached at email@example.com.

run engine until problem occurs. turn engine off or let it die. leave key on but don't start engine. put a paper clip in diagnostic plug under steering column. look at area on dash where service engine soon flashes. count flashes. (ex. 1flash-1,1 flashes=1,2. if you see 1flash of service engine soon, then 5 flashes in a row the diagnostic check = 1,5. It will flash this several times in a row. this is your code. look it up or ask and find out what it is. this is usually your problem area. let the car tell you.
