Could be a sticky EGR valve, or a large vacuum hose off or burnt.

SOURCE: 2003 Chevy Trailblazer 6 cylinder

check the transmission fluid, should be a red handled dipstick or it may have transmission right on the T shaped handle. If ya pull it out and it's a dipstick the fluid should be redish but it may have nothing on it. Has to be checked with vehicle running. I got a block away and around the corner in mine when it just came to a stop and just revved. The guy behind me saved me cause he just happen to sell transmission fluid and had the big jug I needed to get my beast moving again. hopeful that's all it is. good luck

SOURCE: My 02 chevy trailblazer's rpm fluxchuates when

Many of the 6 cyl. engines are prone to carbon build-up in the throttle body. If this is the case, it is best to clean it off the car and is fairly easy to do. Remove the snorkel, 1 electric fitting on the throttle body (a little tricky) and one vacuum line on tb as well. Four bolts remove the tb from the engine and the throttle body can be cleaned with throttle body cleaner from any auto supply store. An o-ring attaches the tb to the engine so that you will not destroy a gasket during the repair. Pretty easy and should take less than 1 hour, but be careful of sharp edges in the throttle body.

I have a 2006 chevy trailblazer i change all the mounts inclunding the idol tentionor and its still vibrates and make niose when am in drive or reverse in park and neutal its fine but just when am in

If the harmonic balancer wobbles when the engine is running, it could cause a vibration. A typical balancer has a rubber seal between the balancer and the belt drive pulley. The rubber seal may have deteriorated.

1977 chevy with a turbo 350 slipping out of gear

Check the TV (throttle valve) cable, if that's out of adjustment the trany will think you want passing gear. Try disconnecting the cable at the carburator, that should make it shift into high gear at about 25 MPH and stay in high until you slow down. If it fails to stay in high gear then you have major problem. Are there a lot of miles on it? Are you sure you have enough fluid in it? Does the fluid smell burned. It might be just worn out. Good luck!
