86 Olds Cutlass Ciera misfire help

[platinumfossil]

1986 Oldsmobile Cutlass Ciera with 2.8L fuel injected engine and auto tranny. i've had this car for a little over a year now as a daily driver of about 30 miles/day and decided it needed a little TLC with the oil change that was due. changed the oil yesterday and went to napa website and found the correct spark plugs, wires and distributor cap for the make/model/engine i have. picked the items up and installed them this afternoon and the car ran normally. before the work the car ran pretty good for me with the occasional stall (once every few days at most) whether hot or cold engine; figured this was a minor idling issue. after the work the engine is missing and the car stalls pretty much anytime i slow down for a turn unless i keep one foot on the accelerator and one on the brake to keep the rpm's up. starts ok but will stall if i don't keep the rpm's up. i found the firing order on the autozone website and confirmed that i have the plug wires on the correct posts on the distributor cap. also noticed that my "service engine soon" light pops on after a mile or so of driving and stays on. and now the cruise control won't engage; i've never had an issue with it before.
i'm about 40 minutes away from the nearest parts store so i'd like to try to figure this out without making that trip, plus my weekend is now over and i need to go to work for the next 5 days and don't want to drive the car in it's current condition. thanks in advance for all advice and suggestions, please help me out!
