My 95 GT keeps getting the same oxygen sensor codes even after I replaced them. The computer memory has been reset and the codes keep coming back and I still get pre-ignition. Could this 'lean' condition be due to fule pressure low or bad injectors? How do I check the fuel pressure?
Any ideas would be greatly appreciated.

If you ever get codes for both O2s then 99% of the time there is a problem elsewhere. My first guess would be the MAF. Are you getting any codes for it?

Yea I would bet something with the MAF is wrong. You may try cleaning the element or swapping a different MAF onto your car if you know someone with one.
