Sluggish after rain
 
Hey just joined, I have a 2010 jeep wrangler sport 3 liter v-6 auto. I noticed during rain / immediately following rain - jeep starts ok, but seems like a miss, very sluggish accelerating, for the first few minutes, engine will not rev above 700 rpms. after a good 15 minute warm-up things are better. Dry days are perfectly fiine. Any thoughts, anyone feeling the same?

Thanks

Is your airbox sealed up tight? Check the oil, any water in it?

What he said... plus look for broken, cracked or otherwise failing ignition wires. Check all ignition components... High humidity makes high voltage do weird things. Open the hood when it's wet in the dark...look for the telltale arcs... Tune low in the AM band on the radio...any ignition noise?

And welcome to the Forum...!

Most engines run better after a rain because the air is more dense. My guess is that you have electrical wiring connection problems. Your warranty should fix this for you.

Thanks for good suggestions - will check each out.

Yep, moisture collecting around the coil packs or ignition wires is probably the culprit.

Following up ... Thanks you for all the great suggestions. During the heavy moisture yesterday, the jeep acted up, in short, the top left spark plug wire connected to the "distributor?", was arcing to the alternator bracket. A quick twist of the boot and viola!

Thanks Again!
Jim
