Thunk sound when gas pedal depressed or ac turned on.

Thanks! Funnily enough after reading reviews, I was planning to give you folks a call at 8am today!!! What chance! I am going to get my battery tested as well today. Forgot to mention it seems like it may possibly a vacuum issue but can't figure out which one as the n18 is ok and the boost is great. everything is running fine its just the suction cup thunk sound when the gas pedal is depressed for a second from idle and of course the ac button pushed.

We have a very tight schedule today but we could sure get you on the radar for next week. If there is a time you could leave it for a morning or afternoon, we can help with a ride or what ever it takes. It would our privilege to help. 360.733.2721 Keith Cox Autobahn - Dan or Becca can talk with you to find a time that works. We can test the battery for you, also.

See ya on Tuesday morning :)
