97 Mazda Protege chugs when it rains until engine drys out, if too wet won't start. What can it be?

Question

Changed plugs, wires, and cap, put $2000 into engine and still can't figure it out.

Answer 1

check for water getting in or on the cap. spray it down with silicon spray and see if it fixes it........other than that i would have a scanner hooked up to your cars computor next time it rains to see if the pcm is getting all the voltage it needs. your gonna have some fun.

Answer 2

Wow, 2000 bucks worth of throwing parts at it makes the one hour 75 dollar diagnostic fee from a local repair shop seem reasonable now doesn't it? Take it in for repairs, save time and money.
