IF by reasonable then with the cost of a distributor and a inlet manifold suitable for engine coming in at around $800.00 dollars with out the headache of trying to get it all to work then I suppose it would be reasonable.
yes, it can happen. check for spark from the number one coil using spark plug wire and hold it near a grounded point. it should be a consistent spark with engine running. compare to different coil wire for verification. those coil packs are partially replace able because each coil fires two plugs. replace the no.1 portion with a new one from parts store. 28.00
If 3800 engine the timing is 1-6-5-4-3-2
If 2.8L or 3.1L or 3.4L timing is 1-2-3-4-5-6
Coil packs on 3800 are (1 / 4, 5 / 2, 3 / 6)
Coil packs on 2.8L or 3.1L are (1 / 4, 6 / 3, 2 / 5) 1995 earlier across the front from right to left.
Coil packs on 3.4L are (5 / 2, 3 / 6, 4 / 1) 1996 across the back from right to left.
run engine until problem occurs. turn engine off or let it die. leave key on but don't start engine. put a paper clip in diagnostic plug under steering column. look at area on dash where service engine soon flashes. count flashes. (ex. 1flash-1,1 flashes=1,2. if you see 1flash of service engine soon, then 5 flashes in a row the diagnostic check = 1,5. It will flash this several times in a row. this is your code. look it up or ask and find out what it is. this is usually your problem area. let the car tell you.
Here is a diagram of the firing order for you 3800 engine. Cylinders 1 and 4 are misfiring because the operate under the same "Coil Pack" and the coil pack has unfortunately gone bad. O'Reilly sells them for between $30-50 depending on the amount of warranty coverage you want. To replace, simply unscrew the screws that hold the coil pack in place. WAIT before unplugging the plug wires. Place the old coil pack and new coil pack next to each other, unplug one plug wire, then plug it to that same port on the new coil pack. then do the same for the other plug wire. Then screw your new coil pack in place, and start you car. should run fine!
