What would cause my 1994 buick lesabre to have a lunging movement when driving, hard time driving, stalling while in idle at a stop, fluctuation of speedometer, and the volts temp oil and check engine lights to come on

Try cleaning your throttle plate and iac valve hole with choke cleaner. They get sticky and do that. Hook up all air ducts after cleaning.

I had same problem.I took 2 months taking car apart and found 2 problems one is crank shaft sensor( when it gets hot it shorts out. So when you get a computer to check it it says its OK) The second item took the longest to find. Its the female side to the wiring harness plug mounted on the fire wall you can check this by loosening the center bolt and gently wiggle the male side of the plug the engine will start or cut off. The socket that the pin goes into have a bent piece of metal used as a spring for the pin to lean against ( they break from to many amps making the metal fragile) so the worst ones are the injectors, the comp. Runs on the ground side so you will find power but no ground.I wired mine to eliminate the plug altogether runs great.
