I just got in from work, and had a few spare minutes to look online, in hopes I'd learn something... so I'm going to change out both front sensors and hope that fixes the problem...

 

Is it spark knock or rod knock?

Bad O2 sensors wont cause either form of knocking.

 

to be honest with you I dont know for sure. I bought the car used back in November.. January time frame the CEL light came on with no noticeable change in performance... it started tapping knocking in probably june, so I changed the plugs and oil, and it (noise) went away... in the meantime, the CEL would turn on and off intermittently, so I figured it was just a bug, since it seems to be in the TSB's.... as August rolled around, the noise came back... I was blaming it ion cheap gas, but the CEL light has been on solid since mid July, when I stopped at Autozone to see what the problem was, hence the p0133 & p0153...

 

I was only getting combined 20mpg for the past few years. Then last month, the CEL came on. I had the knock sensor and purge valve replaced and recently I got a combined 24mpg. Of course, with the increased peppiness I also started hitting the gas more later on and it went down to 17. But it did that too when I bought it new in 94.
