Hi,

Often times when the traction control turns on, it is related to a wheel speed sensor. Were there any codes other than the misfire? When you scanned the computer, were you able to scan the can-bus? CAN stands for controller area network. Basically, all the computers/modules are tied together via a few wires. This type of scan will retrieve codes regardless of the one storing them.

Here is a link that explains how it's done:

Let me know if this has been done, if there are any other codes, and if the ABS light is on.

Take care,

Joe

No other scan has been done. I'm going to click the link and see how.

Hi, Tracy,

OBD stands for On-Board Diagnostics. It refers to the automotive electronic system that provides vehicle diagnostic information. The ABS stands for Anti-Lock Brakes. They are two separate systems, but diagnostic codes from the ABS can be retrieved using the OBD. (If that makes sense LOL).

So, the two things, the cylinder three misfire and the ABS are not likely related.

I want you to try something. The misfire could be the result of a faulty ignition coil. So, switch the cylinder 3 coil with cylinder 2. See pic 1 below. I highlighted the numbers 2 and 3 coils. If there is a problem with the number 3 coil, the misfire will move with it to cyl 2. You will need to have it scanned to confirm if it moved or not, but most parts stores will do it free of charge.

All you will need to do is disconnect the electrical connector at the two coils and then there is one bolt holding each in place. Remove the bolt and gently (while twisting back and forth) pull straight up on the coil to remove it. Install is the reverse.

Let's focus on one thing at a time. Once we get this issue resolved, we'll move on to the ABS.

Let me know what you find, if you have questions, or if I can help in any way.

Take care,

Joe
