Not saying this is the issue, but the torque converter has a lot to do with your shifting and ability to get up to speed.

I have had the same problem. When I would come to a light my rmps would drop to about 400 and shake. It had 36700 miles out of warranty. They said it was still within the specs and since out of warranty they could noth. $300 they clean throttle and fuel rail and reset computer. 15,000 miles later it began to stall at light about once a week. I refused to take it in, but when it stalled turning left in traffic I had no choice. I told GM Service that I would not pay 300 dollars every 15,000 miles. This time only 89 dollars. They claim that they could not find anything wrong with it because no check engine light on. I also noticed when it was having these problems if you put it into neutral when getting on the highway the rmps would bounce between 400 and 1200.

It'll stop pretty soon as there won't be any left.

The dealer tried to calm the rough idle down about 5 times by reloading the computer. After 5 times they said that there is NO fix for the problem and that it is a normal characteristic of the vehicle. I don't think there is enough money for GM to put fourth the effort to help their customers. I guess the lawyers will have to see if its a problem or not. My truck looks cool but is a pile of crap. The lighting doesn't work right, my window wipers go off whenever they feel like it, and now the truck has a rattle sound in the engine when driving.

hi i bought a 2005 colorado with 61,000 miles on it i had it 1 week then the motor wasnt idling right i brought it to chevy and they said there was a recall on all the 3.5 5 cyl motors they had to put a new cly head on it. so if you know anybody else that has this problem gm has to fix it for free 10 years or 100,000 miles on it at first they were trying to keep it quiet but they could not. and just hope they dont break the cam sensor like they did on mine . that took a week to get that part.

Everyone who own them at the time was sent a letter on the problem so it is well known and a few here have had the problem fixed.

I received "the letter", and it's safely tucked away in my truck's glovebox. Hopefully, I won't need to use it, however at the rate I put mileage on the truck, I'll never get anywhere near 100,000 miles on it within the 7 year period.
My truck is 4 years old this month, and I'm just approaching 26,000 miles. Knock on wood, it's still running well.....
