Welcome, I'm Chris (aka Moose).

  • Although I work here everyday, please understand it is not all day and rarely morning time.
  • To get the most from me and the best experience, please give me the best details you can.
  • The website will offer you a phone call option for more $$. Some I do fulfill and some I do not.
  • Thanks, let's get started. If I upload dropbox links, without the app use the box in the top right for direct download.

Based on low power and exhaust noise. Your issue may be a restricted catalytic converter either from soot or an internal broken baffle. I suggest you run it on stands or a rack so you can look and listen from below. Next, remove the upstream O2 sensors for a short road test to see if the power is back which will confirm a restricted converter.

Now that I have posted a partial or complete answer, you will see you can rate me. The deposit you have already paid is not transferred to me until you rate me. I would like to receive nothing less than 5 star excellent ratings. So if we are not there yet, please reply and let me help more. If you're not pleased, let me know because rating bad does not result in a refund, there are better options. Rating now will not close this post nor prevent replying. Thanks Chris

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.
