I reccommend putting WD40 or CRC on the connections to stop them corroding over time. You also want to make sure the Distributor Cap gasket seals well to keep out water. last make sure you don't get the leads mixed up, best to replace them one at a time. cheers

First thing you need to know is which cylinders are missing. Then, don't forget there is an engine beneath the electronics. Do a quick test with a vacuum gauge and do a compression test. Check the distributor shaft for side play. If everything checks out good, then do electronic component testing. have a code check run (many parts stores do this free) and get a chiltons or haynes manual and follow test procedures in there.
I refrain from giving repair suggestions with problems like yours because people keep changing instead of testing parts. When I work on my vehicles or other peoples cars, I do testing to avoid buying expensive parts that most times won't correct the problem. At this point the most I'd suggest is to clean the mass air flow sensor wires with a Q-tip and carb cleaner...that often helps and is free. If you run into a problem with whatever you find, ask and I'll try to help.
good luck

Don't know your engine size so pick the correct one for your motor:
2.3L 4-Cylinder Engines Firing Order: 1–3–4–2 Distributor Rotation: Clockwise
2.8L 6-Cylinder Engine Firing Order: 1–6–3–5–2–4 Distributor Rotation: Clockwise
2.9L 6-Cylinder Engines Firing Order: 1–5–3–6–2–4 Distributorless Ignition
2.3L and 2.4L 5-Cylinder Engines Firing Order: 1–2–4–5–3 Distributor Rotation: Counterclockwise
Testimonial: "It ism still missing on #2 cylinder."

Check #2 injector for proper operation. If thats ok, test the Distributor assembly and crank sensor for proper operation. These components control fuel and spark timing!!
