I have a 92 Camery with a 4 cyl. that for some reason dies when giving it gas after slowing down only when it is raining. It sounds like it starts missing really bad before stalling. I have replaced the plugs, cap, rotor wires and even the throttle position switch but with no results. The fact that it only happens when it is raining leads me to think it is something electrical, but also makes it hard to schedule a time for someone to look at without knowing the weather a week before hand. Anyone have a similar problem? Any help would be great.:) Thanks.

The ignitor is a possibility.

your vamry proble is a bad ignition ccoil.

When my Camry had a bad ignition coil, I had similar problems. Eventually, it wouldn't start at all in the rain. It's a bit expensive to replace, unfortunately. :/ Spraying WD-40 on my distributer every day helped ALOT, but it was only a temporary hack/fix for me and it eventually stopped working well enough. You could try that as a diagnostic maybe.
