so i have a really bad vibration in my car when im driving in the rain. it only happens when its raining. it gets so bad at times that it shakes the center console. it does it while im at a dead stop as well. ive crawled under the car and checked everything i thought it could be but still nothing, ive asked friends and chevy cant reproduce the issue so it "doesnt exist" anyone have this issue before or have any ideas what it could be?

If it's exactly as you describe it I'd look for a plug wire that gets shorted when it's wet. Might take a water mist bottle and spray the coils and wires one at a time and see if a misfire starts on a dry day. Silicon spray sometimes can waterpoof wires but if it already has some insulation rub through it needs to be moved and or replaced.

Sounds contradictory. Trolling?

I have 100% had this same problem. Only happens in the rain when my drivers side tire hits a puddle. I have narrowed it down to possibly being the large amount of water landing on top of the header collector on my long tubes and rapidly boiling and popping and hitting the heat shield. It becomes quite violent

I removed the heat shield.

I have a friend that drove his '12ss here from Houston last Wednesday and had the same issue. He said it was pretty scary 75mph.

Bring it to the Dealer on a rainy day and take them for a ride to reproduce.

definitely not trolling. the part I said about driving just fine while its vibrating was reffering to the spark plug wire, I was saying that the engine performs just fine as in its not misfiring but the vibration is still there.

Do you still feel the vibration if you push the clutch in ?
