Hello,
I just got my 07 MDX's timing belt changed at dealer 2 weeks ago, and now in the morning, when I turn on the ignition to start the engine, first of all I will heard a very loud "bang" like sound, it's more like from under the wheel or ignition, then engine will start. I didn't notice this problem until lately I did the spark plugs, so it comes more often than before, it happens now every morning when I start the cold engine. And it will disappear if I try to start the engine again when it's warmed up.
I tried to call the dealer this morning, but nobody answer the phone. So just wanna get some initial idea before talk to them.
Any idea or help will be very very appreciated.
Thanks
