Damn rain
Well, my car runs perfectly. Except when it rains. She sputters and almost stalls when giving moderate throttle and starts harder. I also threw about 14 codes for miscellaneous things the other day. I'm sure there is a bad connector or bare wire somewhere. Damn it. I'll post the codes later, but they are all over the board and probably won't help diagnosis much. Tracking these electrical gremlins can be tedious work. If I lose my patience, I might have to take a C7 out for a test drive and see what all the fuss is about lol

The PCM is located in the passenger side fender where the door and fender area meet. It is actually not uncommon for moisture and water to get in there if say you are not aware of if that area is still completely "sealed" from elements. The PCM controls a lot of driving functions of your vehicle, and most of what you're describing is resultant of moisture issues (it's similar to the old C5 battery issues when initially they could drop battery acid into this area and damage the PCM and it's wiring).
Personally I would remove the passenger fender and see if the PCM and it's connectors are still sealed.

Two good suggestions above. If this is only happening when it rains, some electrical connection(s) are probably getting wet.

Okay this may not be a contributor but if you an airaid filter or similar you could be getting water in the intake when you drive. If that's the case a hood seal will fix it. How do I know, it happened to me. Just a guess, don't know your setup.

I didn't feel any moisture on the floor at all. Someone mentioned an airaid filter a few posts back, which I have. Maybe water got on my MAF? I'm willing to put some more money into her, but at a certain point it won't make financial sense to me. I wasn't driving through puddles which pisses me off. I love the style of the C5, but not sure I made the right choice when buying my dad's 17 year old car about 4 months ago. I'll have some cash to blow later this year. Just not sure if I want to go all the way with the old girl now, or just say f it and buy a new one. I'm going away for the weekend, and dropping her off at a shop tomorrow to see what's up and put some new miscellaneous stuff on her. I'll report back with the findings for posterity. All comments and insight are appreciated.

I mentioned Airaid filter which you have, I'm telling you right here and now you need one of these. https://www.amazon.com/Z06-Corvette-...ag=d_2b_a_o-20
