Traction control service JA: Sometimes things that you think

Customer Question

Traction control service
JA: Sometimes things that you think will be really complicated end up being easy to fix with a Chevy. The Chevy Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.
Customer: Traction control service and my truck shakes at times when I'm fully stopped on a red light
JA: Are you hoping to fix this yourself?
Customer: Yes
JA: Great! What have you tried so far?
Customer: Been looking at youtube videos and one dude said its the break light switch
JA: Is there anything else important you think the Chevy Mechanic should know about your Chevy?
Customer: Stability track service and it has the check engine light on
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Chevy Mechanic about your situation and then connect you two.

Hi,First, what year model and engine size is your chevy?Have you had the computer scanned for misfire/trouble codes?
Customer: replied 6 months ago.
2007 Chevy Tahoe ltz 5.3
Customer: replied 6 months ago.
Have not scan codes
Expert:  Jared D replied 6 months ago.
Oh, the 2007 5.3l. I hate to be pessimistic about it, but it's a pretty safe bet that you have a valve-train problem. This is incredibly common on the 2007 tahoe. One of two things happens: a lifter seizes causing a misfire, or a valve usually exhaust burns and then causes a misfire. The result is a service traction system indicator and sometimes a blinking check engine light at an idle. I had a mechanic friend of mine trade his tahoe in for this very same reason.Do you plan to diagnose/repair it yourself?

I plan on diagnose and repair it myself

First you will want to get a hold of a scan tool and hook it up while idling so you can do a power balance test and see which cylinder is contributing the most misfires.From there we can test that individual cylinder and see what the problem might be.
