Hello, welcome and thanks for asking your question. My name is*****'ll be assisting you with your question today. Please give me a few moments to review your question. Also keep in mind that I do not know your skill level or abilities so I may be asking a lot of questions before I can answer. In some cases we may need to respond to each other quite a bit before I can come up with a possible solution for you. As far as phone calls, If you didn't request it, it is most likely the Website prompting you, not me. A Live Call is a "Premium Service" and will cost more money. I prefer communicating via this site, but in some cases a phone call may be recommended.

Is the check engine light on? Has it been scanned for codes? If not The best thing to do at this point is to scan for the "Diagnostic Trouble Codes" (DTC's) from the onboard computers. The DTC's are used as the Starting Point for diagnosis. They let you know which system(s) the fault is in. This information is of great value for correct diagnosis. As a Technician, my first course of action is normally to scan for the DTC's. If you can obtain these codes, we can more accurately and efficiently diagnose the problem. You can have these Codes read for FREE at your local auto part store (AutoZone, O'Reileys, Advanced, etc.). If you post these Diagnostic Trouble Codes here, I can obtain the most accurate information to help you diagnose the Concern, and then point you towards the correct repair.

Keep me posted...

Thank you,

Robertn

What Customers are Saying:

I AM VERY GLAD THAT I TOOK A CHANCE ON YOUR PROBLEM SOLVING SKILLS. I WAS SUCCESSFUL IN REPLACING THE FUEL PUMP. MY TRUCK RUNS LIKE A CLOCK. IT RUNS LIKE THE DAY I BOUGHT IT. NO LUNGING FORWARD, THE TURBO REACTS THE SECOND I STOMP ON THE GAS, AND IT HAS A LOT MORE POWER AND EVEN SOUNDS BETTER TO ME. IT SAVED ABOUT $500.00 BY DOING THE WORK MYSELF. I GIVE YOU ALL THE CREDIT FOR YOUR DIAGNOSING THE PROBLEM, JUST FROM THE SYMPTONS I GAVE YOU OVER THE e MAIL. I WILL USE YOUR WEB SITE AGAIN AND REFER MY FRIENDS. THANKS SO MUCH FOR THE HELP.
