All of a sudden it is missing a bit. Shakes from running ruff. Not as much going 30 mph but more as I go faster.

I would perform a tune up on it. Make sure the plugs are good. The plug wires are good. Air filter is clean and lastly that the fuel filter isnt clogged up

You were just driving and all of a sudden it started hesitating while you was driving it or you parked it one day and the next it ran bad.

Yes, but it rained for 2 days and there was alot of deep water. My check engine light flashs and I am told it is from missfireing. It is smokeing a bit I think, its only 37 outside so I am not sure. I get a wiff of unburnt fuel. Im thinking its in the coil or coils, but I am hopeing for a simpler problem. And now I worry about ruining 1 of my cadalitic converters, if not both. Simply I am a poor man with only the 1 ride. Also my plug wires seem in tact.

Sorry, it ran fine. About 3 miles, then I parked it. The next time I started it, a few hours later, it ran bad.

Did you drive in the deep rain where it could have been thrown up under the engine compartment?

Yes I did the day before, it ran fine the next morning to work and back. About 6 miles total. I looked at everything and all seems dry. Im putting it in the shop thismorning. I just dont want to be mislead on what I actualy might need. Still hopeing its a tune up thing and coincidental. But I fear a greater problem.

After knowing bout the large amount of water it could be causing a short in a sensor or module. Hopefully it doesnt get far enough to fry pcm.

What they tell you to have replaced you can always get back with me and I can tell you if its a possibility or if they leading you around
