My engine started making some clicking noises, the acceleration is bad (rpm goes high to accelerate) and rpm's are unstable when slowly accelerating on the highway.

Thanks for the video, it makes my job way easier. It looks like you lost the timing chain guide. I assume it has more then 31,000 miles on it?

You will need to pull the front balancer to get started.

Then remove the front cover and check for damage, I would replace the chain and all guides while you are in there. If you have the job done it should run about $1,100.00.

Check out the diagrams (below).

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken
