I have a 2003 CL and have been experiencing this problem for more than a year now. During this time, I have tried a few things and performed fixes of other problems (thanks to the wonderful guides in this forum!) which I will list below. When I'm driving between 50 and 55mpg (some times between 50 and 60), the car shakes dramatically, usually during acceleration. I can overcome this by giving the engine more gas. This happens regularly every day and I'm worried I might have a transmission problem. The car now has about 165K miles on it and when it was < 100K, the dealer replaced the transmission under the recall. The transmission fluid is only slightly dark, almost appearing as it did when it was new, and there is no "burnt smell."
I haven't found anyone else on these forums who describe this problem quite the way I am experiencing it so any advice would be greatly appreciated. Thanks!
-Replaced ignition coils
-Replaced fuel pump
-Replaced fuel pump relay (car wouldn't start in the hottest weather)
-Regular oil changes and 93 octane fuel every time
