Hello everyone. This is my first time joining/using and post, but I have a problem with my Honda. I've research and have found no answers. So Here it is. I went to the Honda dealer for a normal oil change. They came back and told me that my serpentine belt needed changing: afterwards my dashboard lights came on. CHECK ENGINE, TRIANGLE, VSP. took car back and $1500 later they replaced timing chain, tensioner, o-rings, oil seal, gaskets, and spark plugs and other stuff. My car that use to run smooth, and get good gas mileage could go 60 miles round trip gas hand barely moved. Now with new parts it runs rough, on a full tank of gas, drive 60 miles round trip come back half a tank. I practically put $30 a week. When $30 use to last 2 weeks. Looking a videos if the timing chain isn't lined up with all the arrows that could effect the engine. Also on cold start it makes a loud ratting sound then goes away. Ok guys do you have any serious Ideas. Or did they take the old lady's money. Thank you
