I am experiencing a new problem on my 99. I will be cruising along at 45-65 and my engine will surge like a transmission slipping. It only does it once in a while, but seems to be more often. Also this Morning on my way to work my cruise control kicked off with out my touching the brake.
My guess is a sensor..
Any advice will be great.
Thanks ???

 

I would try the apps reset procedure first to see if that helps with anything and then go from there if you have to. The apps reset procedure seems to help with some issues similar to yours. You can do a search on this site to find the exact directions. It is very easy to do and best of all it is free! Good luck.

I am now notice it only seems to happen when I am using the A/C..
