Question about 2007 Chevrolet TrailBlazer SS
A ticking started in the motor under higher rpm's? It only has 29,000 miles, So, I took it to a Dealership dropped it off. They said they could not hear it. I picked it up on a Friday night and drove 1/4 of the way home, the sound became worse? It was to late to turn back and I had the car towed home to be safe. I am not sure what to tell them, and should I go to a diffrent Dealership!
sounds to me like your coil packed it in or your timing belt ( chain ) has jumped a tooth. If you have access to a scanner run a diagnostic check on your car to see if it comes up with any trouble codes.

the first place to start is the flashing engine lite. that means cylinders are not firing at all or improperly and driving it like that for even short period could cause heavier damage. particularly valves and cat converter(s) the computer really needs to be scanned for codes in order to proceed. did the oil lite come on before or after engine quit. after engine quit would be normal cause it stalled. its possible that it needs spark plugs and/or coils. or more

CHECK your Distributor....Or have YOur alternator,starter,and battery professionaly tested at your local pepboys...If you bring in your parts on hand its free....if you bring in you vehicle then it starts....

My first guess would be the front u-joint on the drive shaft. Try twisting the u-joint to see if there is any play, which there shouldn't be. If the u-joint is OK, have the transmission checked out at a reputable shop. There could be a problem with the torque converter, the valve body, or the bands. You didn't say whether this was a 4 wheel drive or not, but I doubt that the problem is with the transfer case. Let me know what you find.

SOURCE: suddenly running rough
Well, it could be a couple of different things. The "jump timing" theory would have a poor engine performance and engine miss associated with it. So I don't believe this is the problem.
If the ticking or knocking sounds like it is coming from the top of the engine, you have a clasped lifter, bent push-rod or rocker arm problem.
Is the noise present when the engine is cold or hot?
Make sure the oil does not look milky.
Let me know.
