Need help with an idle problem on a 2006 trailblazer

I just replaced my sisters thermostat in her 2006 trailblazer, in doing so I had to release the serpentine belt and now it is all back together and it started fine, but now the idle is off and it bogs down and cuts off. What could be the problem? how tight do I have to make the bolt on the outside of the tensioner? Thanks -Benny

The belt should be on an automatic tensioner ,your problem is not in the belt but it is possible you have air in the coolant system and the coolant sensor is not submerged and therefore will not allow engine to reach maximum rpm's,try running engine up to temp while the coolant cap is off and wait for all air to come to surface.that should solve you problem. good luck.

My 2006 Trailblazer EXT LS gave a p0017 engine code. I replaced the camshaft sensor and it still has a rough idle and hesitates until you get up to 35mph. What should I do now?

Poo17 is for sensor b therefore you have a senor a on the cam as well and it maybe creating the problem. you need to check it as well. The code for cam senor a is poo16. If it runs rough when you start it you may have a bad idle air control or engine tem. control which tells the computer what the temp is outside and determines how much fuel is put into the engine. I would check the idle air control first.

How do you change the headlight bulb on a 2006 Chev Trailblazer

When you open the hood you will be looking straight down at the light lenses. On both sides of the lense body on the top you will see two small steel clips. Lift the clips up and this releases the lense body. You will now be able to pull the body out straight toward you. You may need to wiggle it around a bit as it has a habit of jamming up on the wheel well side of the vehicle. Once its out grab the light harness and turn it counter clockwise and pull it out. Repalce the bulb and reverse all the instructions to replace the body.

Idle problem on a 2006 chevy trailblazer 4.2

The code indicates an issue with the Throttle Actuator control. This is a little motor on the throttle body that opens the throttle plates at idle. That control motor may be bad and thus, causing a low idle.

I hope this helps.

P0172 and P0128 Error Code 2003 Trailblazer 4WD

PO172 means that an oxygen sensor in bank 1 detected a rich condition (too little oxygen in the exhaust). I would replace the thermostat first. The computer could be injecting too much fuel because it thinks it never gets to operating temperature. That may keep the light off.
