Too much gas and no power!

Hello,
My 95 4Runner SR5 3.0 V6 is getting about 5 miles to the gallon and has no guts after the CHECK ENGINE light comes on. So far, we have changed the knock sensor and the 02 sensor. The timing is right. We've pulled the plugs...all were in good shape,but one was really clean.So, we changed the fuel injector for the lean plug.Still the code is 52. I don't know what to do.Now I'm guessing it is the computer.Any ideas or help would be greatly appreciated. Thanks

 

You should definitely try replacing the Mass Air Flow. I was having a little trouble with no power before but getting a better MAF helped with that. Changing the knock sensor and the MAF should put you where it wants to be, I'm hoping.

 

You know when I first saw this thread title I thought to myself, "oh good! I'm not the only one who's feeling this way."

 

Code 52 didn't have to be a bad sensor. The harness pigtail is known for going bad on that motor.
