Fluctuating RPMs while driving?

Hi,

How often does this happen? The idea that the theft light turned on and then off leads me to think there could be an issue with the key itself. If you have a spare key, try using it and see if it still happens. If it does, then I recommend having the can-bus scanned.

CAN stands for controller area network. Basically, the different modules are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them.

Here is a link that explains how this is done:

Let me know if this is something you can do or have done for you.

Take care,

joe
