I have a 93 bonneville se the problem I have is the car will be running fine then the check engine light comes on and if I take my foot of the gas the car instantly dies. The car always starts right back up after it dies.The light is usually only on for 5-30 seconds then everything is fine again. I checked all my cables and cleaned all the connections but that did not help. I was wondering if it could be a computer problem?

ii had a problem with my 94 sse doing that...it had an egr code and the egr would stick occasionally (It was a linier egr)...causeing it to stall when the rpms got low, i changed the EGR valve and it never stalled again...i would see what the code is and try and clean the egr valve at first...

It could be a bad PCM, but before you do anything else, pull the code and let us know what it is. The method for pulling the code yourself on your 93 is given in Techinfo.

As Mr. Buttermore has asked, let'* have some codes pulled before ANY conjecture. It might be this, it might be that......

Codes, then we'll get to work on it.

93 is different than 94, as mentioned...codes should always be retrieved...even in the case of no check engine light. There are many codes that require more than one occurance to illuminate the light.

I have not had a chance to check the codes yet to cold and we got 8" of snow last night . Gonna try this weekend. Thanks for the Help.

Do that and be sure to give us as much info surrounding the issue as is possible. Better chance you'll get the right help right away.

I finally was able to pull the codes they are 14,23,and 43. Heres what has been happening wi th the car. It runs and drives perfect but the check engine light will come on occasionally and it stays on for about 5-35 seconds and while the light is on if you take your foot off the gas the car instantly dies. It will always start right back up and run fine. If the the car is stopped and the light comes on it does'nt stall it runs fine. I just bought this car cheap because of this problem. Any help would be appreciated thanks.

Hmm...

14 - CTS Circuit - High temp. Indicated
23 - IAT Sensor Circuit - low temp. Indicated
43 - Electronic spark conrol circuit

Plug your IAT sensor back in. It'* in the back side of the airbox. Code 23 is simply disconnected IAT most of the time. It'* easy to overlook when reassembling your airbox.

High CTS is a possible shorted or bad Coolant sensor. You have two. Compare them with an ohm-meter. They should be very close to the same resistance when measuring to ground.

Code 43 could be an ICM, cam or crank sensor, or a bent tab on the back of the harmonic balancer (or associated wiring).

Considering all 3, it may benefit you to carefully inspect your wiring harnesses where they enter the firewall on the passenger side of the engine bay.
