Question about 1992 Cadillac Brougham

Vehicle missing at highway speeds

My 1991 cadillac brougham d elegance stutters at highway speeds.i can drive around all day at regular speeds and it will never happen.once i get on the highway for about 2 or three minutes the check engine light comes on and it starts missing if you will.It used to only do it one time then the check engine light would come on and it would'nt do it again.Now it will cut in and out repeatedly with the chesk engine light coming on and then off when i step on the gas.As i let off the gas the light fades back to full brightness.Some forums make it sound like throttle position sensor issues.If you try to use cruise control at any speed any time it will start to go crazy giving gas and letting off very wildly.

HI. I HAVE 1991 cadillac brougham , problem is the seatbelts are not working, when applying break while driving or pulling it by hand will not lock,May i know the exact issue please


On some vehicles the momentum of the vehicle must be slowing down for the mechanism to lock. Sometimes on older vehicles that must be a drastic slowing down. Like if you were braking to avoid hitting something.

THE CAR DISPLAYES ANTI-LOCK BRAKE LIGHT THEN SHUTS OFF IMMIDIATELY AFTER 91 FLEETWOOD CADILLAC , BROUGHAM


I am assuming this is while you are driving the vehicle? The light should come on and turn off at start up, as the ABS computer runs a self check. If the issue presents itself while driving, it is likely a wheel speed sensor that is starting to fail. If the computer looses the signal it will turn on the dash light, when it sees a signal again it will turn the light off. Could be a broken wire between the chassis and wheel speed sensor or a bad sensor. If you can, check the ABS codes, they should be stored.
