Possible coil pack on one or more of the cylinders. A code may not show up if a coil pack is bad.

Good luck on this repair.

Rpms rough


That kind of engine speed change is usually caused by a vacuum leak, most likely around the intake manifold.

89/98 olds. regency. its runs for awhile and then shuts off. it also backfires through the exhaust at high rpms


Probably timing. Aim a timing light at your crankshaft, and see if the mark is jumping back and forth irradically. It should be staying in one spot. If it's jumping around, your timing chain has jumped a cog.
If not the timing, then it's probably bad wires or improper firing order .

Rpms bounce up and down while accelerating


When bouncing, does the engine speed go up and down. If not, the gauge may be bad, or if the engine sounds like it speeds up, try cleaning the throttle body by spraying throttle body cleaner into the intake/throttle and wipe clean with a clean cloth. Do this 2x's. You will have to remove the intake pipe that connects to the filter box and intake. After cleaning this, it may seem hard to start for a second, it's because of the cleaner. Don't worry it will start.
