"Why is the engine bogging under acceleration?" için yanıtMine is doing the exact same thing!! It will get to about 30 mph no problem, but then immediately begin to loose acceleration and slows way down. Then, if I let go of the gas and let it idle almost all the way down and then hit the gas back, it shoots right back up to about 30 mph only to drop speed right back down repeating the same process over and over. My mechanic tried everything you can think of to no avail. Now he's saying it is probably the timing chain because he eliminated all the little issues it could have been. I wish I knew for sure and that he wasn't ripping me off, but most people on this thread have not brought up the timing chain, so it's not giving me the advice I was hoping for. Wish someone knew more on here!
