Engine Stalling '93 Cavalier RS

Have a '93 Cavalier RS - 3.1 litre engine. 144,000 miles (240,000 km) Has always been running excellent until recently - engine has been stalling. Engine begins to sputter and sometimes misfire and then eventually stalls.

Local mechanic does a computer scan and says car needs tune up and replacement of coil pack. Starts off with tune up, but it does nothing to solve the problem. Should I waste my time and money replacing the coil pack? Would appreciate if anyone has any ideas or has experienced similar problems. Thanks.

My 91 was doing the same thing. It would start missing and would stall. It would start up and run fine for a few miles then start missing again. I replaced the control module and that fixed the problem.

The tune-up is never a bad idea,but there is probably a code set in the comp.that should point you in the right direwction.
