1994 Oldsmobile Achieva misfires, cuts out

With problems at idle, check for a leak of some kind? Fuel leak--egr leak--vacuum leak. If your fully obd1 compliant, you can check codes, yourself. You use a jumper wire between the A & B terminals at the datalink connector. Turn key just till the dash lites on, no further, then the mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes.

With misfire check fuel-- spark--compression.
