The sound I have is a lot louder. Again it started as a lifter tick then got worse. The sound it now has is much louder. Basically what happened to make me park it, was when I would accelerate too quickly, it would bog out kinda. Even stalled once. Then finally driving on the highway, I was trying to accelerate but I was starting to go slower. Then all the sudden, KNOCK KNOCK KNOCK. And keep in mind, I just had an oil change maybe 200 miles before that. Before that it was 8000 miles
