My jeep hates the rain

For the past six months if it raining or some what damp out my Jeep runs like crap. The engine seems bogged down and I experience occasonal power loss (engine). I have a 99 4 banger with 127,000 miles. Today the check engine light was in flashing mode for the duration of my 20 minute commute. I have the original c. converter and am wondering if it's time for a new one. Any ideas?

Yep, you need a tune up. My 99 had problems starting and staying running if it rained or temp changed dramtically. I tried o2 sensors, coil, etc. and wasted a bunch of $$. The condensation was building on the sp wires. Grab a cap, rotor, plugs and wires and you should be good to go.

Yup, as emcee5000 suggested, start with a tune up.

The fact that you only have problems when its damp/raining leads me to believe this is your problem.

Just tuned it up about 8 months ago. I checked the new wires, plugs and cap and everything seems to be snug and water tight.

8 months is 8 months especially if you have been through a winter. What type of wires did you buy and please do not say Xact, they are complete junk.

While everything may be snugged down and tight, there may be a crack in the rotor cap that you can't see. Since i see you're in MA, i know you've had three days of rain and probably have five more coming. On one of those days, while it's running rough in the rain, take it home and take off the cap. I'd be willing to bet you've got condensation in there.

I've seen this more times than i can count and it's a large part of why i try to avoid vehicles with distributors any more.
