If you are having issues with you vehicle I would strongly suggest you pick up a service manual, go to the troubleshooting section, it will give some symptons to help pin point the issue. From there you solve the issue with the step by step instructions in the manual or you go to a shop and tell them the issue. I would suggest you fix it yourself if you have the extra time a shop is pretty expensive. If you want to take care of things the RIGHT way I would suggest you go to Carboagez.com and get a service manual. Or at least check them out and see what manuals they have for your ride lol. They are legit there, I have been using Carboagez.com for all my service manual needs since 2006.
