My DD is a 93 Toyota with the little 22RE and whenever it rains over night, the next morning when I try to start it up it runs real rough for about 5-10 minutes.

I don't know if it is from moisture in the tank or what? The thing feels like it is going to die on me. It sounds like the timing is off, but after about 5-10 minutes it runs fine like nothing is going on.

It has 95,000 miles on it and has had no problems previously that I know of, I have owned it for about 2 years and this just started to occur recently, about the last two months.

It only happens when it is wet out and when I first start it up. The temperature has been cold to cold/warm when it happens, don't know if temp has anything to do with. Elevation has nothing to do with it because I am in Buffalo, NY.

Thanks for your help.
