01 Elantra, Visible Arc Damp or Wet Conditions Options

[rie64]

Help!
We have an 01 Elantra (original owners)with 101k. Have had some issues since deer ran into front passenger fender last year - don't know if it's related.
On damp or wet rainy days the car will run REAL rough and check engine light comes on when you first start the car. The first time this happened was the day I picked it up from the auto body shop after being hit by deer. It was pouring that day. Took it out on road and it stopped after a short distance. The guys at the shop cleared the code (misfire in 2 & 3) and suggested I change the plugs and wires. We did that and all seemed fine for a while. We have had this problem now for about a year or so only on rainy or damp days. We had an extremely wet spring and summer this year so the problem has been worse. We again changed the plugs and wires a few weeks ago and are now seeing an arc between 2 & 3. The arc could have been there prior to this last plug/wire change, we just never noticed it. If you drive it a short distance all of a sudden it will run normal and not have the problem for the rest of the day. Seems like there is a moisture issue?? These are brand new plugs and wires, but not from the dealer. Could this be the coil? Would hate to spend the money on a new coil if it is not necessary. Any thoughts?

I'd be replacing the coil since you had misfire on 2 and 3. That indicates one side of the coil is bad. 1 and 4 are on the other side.

Does a coil include both 2/3 & 1/4 or do I need to specify at the auto parts store which one I need?

Update!

All is well now that we changed out the coil pack. We tried to just get the one pack for 2 & 3, no one would sell us just the one side. Probably a good thing to have changed the whole thing anyway. Took the old one out and put the new one in - running like a dream now!
Really appreciate the advice.
