rough idle

I was just wondering if any one else has had a problem with
there lsj in the rain.. every time it rains mine wants to idle rough
and when your accelerating it jerks and shakes and
most of time won't go past 3k rpms.. I've checked for
vac leaks and the intake, I thought maybe the filter was
getting damp but that's not the case cause I don't see where water
would be getting on the filter.. any help would be great cause
it's aggravating

post in problems and service if you are having problems in the future

your maf is more then likely wet get maf cleaner and see if it fixes the problem if it does then get a hydro shield for your air filter

What tpye of air intake and filter do you have? Stock? aftermarket?
Aftermarket dryflow filters are notorious for getting wet and letting water through to get on the MAF causing rough idle and driveability problems in the rain.
Clean the MAF and switch to a oiled filter like a K&N, or get a hydroshield.
