Misfiring..

I just replaced my plugs and wires in the spring. But when it is raining out or high humidity, the car misfires at low rpms. Or the more load the motor gets. Bad coil maybe?

I had the same problem when wet. Under more load or acceleration the car would misfire. You can remove the coil and check on the sides and on the bottom for cracks that let moisture in. Mine had 3 large cracks that you couldn't see unless you removed it. I bought one of those cheap >$20 coils on ebay and it's been running perfect for over 3 years now.

Try pulling a code for which cylinder it is, try swapping coils/checking your spark plug gaps.

*possibly a bad seal on the coil itself.
