Question: Why does my tac jump?

While driving when I let off the gas the tac goes up and down, in the range of about 500 rpm's. I was told it is due to the trans and engine not corresponding with each other properly. The car is also sluggish when starting from a dead stop. Can you help?

Hard to say what the problem is exactly without driving it myself. Your first step should be to check the engine and transmissions computers for any stored fault codes.

Thank you for your response. I took the car in to a Chevy dealer and they say there is no problem. Last week while driving in about 30 degree damp wheather I was unable to stop at a light. The engine wanted to continue to move the car while braking causing the ABS to kick in and pushing me into the intersection a bit. Would the check engine light come on if there was a fault code? Also, at the time of purchase I paid $2,100 for a three year extended warranty but it seems the dealer does not care to work with it. Do you know if dealers and warranty companies have any kind of realtionship?

The check engine lamp will illuminate for most problems but not all.

The warranty should cover any repairs. Not all shops will be willing to work with the companies.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
