Hello everyone, long time lurker, first time posting.
I have a 2009 Silverado 5.3 Crew Cab with the 6 spd tranny. Last February I got it tuned by Justin at a group meet up in Houston. Justin breathed new life into my truck and made driving it more pleasurable. I didn't want to tune it to necessarily race it and burn rubber all the time, I just wanted a better driving experience. Everything has been awesome until last night.
We got some very cold weather here in deep south Texas. It got down to the upper 20's. Sleet, ice and some snow. It never gets like this down here! The truck stayed in the garage throughout the duration of this winter storm. During the day, I went to get something i left in the truck and turned it on and I get a few warning messages. "Service Stabilitrak", "traction control off", "service traction control" and the little traction and engine light came on. I also immediately noticed that the engine was idling a little rougher than usual. And now when I put the truck on drive and let go of the brake, the entire truck starts shaking. I took it for a drive and also noticed that when I'm coming to a complete stop the truck shakes/buckles when downshifting.
What could be happening? I disconnected the battery, reconnected and it didn't help. I have 49K on the odometer. My concern about taking it to the dealership is the blackbear tune. Will they just turn me away? Anyone else have the same kind of experience? Obviously the problem was caused by the weather, but it was never driven during the winter storm.
Sorry for the long post, but as you could imagine, this is frustrating. I emailed Justin, but I got an auto response, saying he would be out of the office until Monday. Plus, I really wanted to know if anyone here on these message forums could give me any insightful advice.
