I have a 04 TB LT and noticed a weird noise coming from the enginecompartment. I recently replaced the spark plugs and cylinder 1 ignition coil. The video was recorded today and it was the 1st start up of the day plus it was around 15 degrees....if that matters. Any help would be greatly appreciated.
Thanks,
Kevin
