Ok. I got my PCM back today from getting the chip reflashed that I messed up....My car has been suffering from very audiable pinging/detonation, mainly in the 1800-2700rpm range...but sometimes everywhere. Sometimes I get some knock retard...but usually not more than .x or a degree...wth. I can hear the pinging and its not pulling any or much timing? Well that aside, i think (according to autotap) that I am running very lean. My O2reading go as low as like 34 and sometimes get to the 800 range. It seems to do it the most in the above mentioned rpm range. I have new O2 sensors and a new knock sensor(as well as about every other sensor...in a neverending search to cure this problem)...so i dont think its them.

The thing I dont understand is my Ltrim will say its running rich(in the negative number percent) but my O2s will say im lean as hell. If the O2s are right...No wonder I can hear it soo much. Also, I have LT1 edit...so If you have any tips?!?! on what I can modify to correct this...that would be wonderful.

Please help me...its sounds so bad, im scared to drive the car and hurt it. Ill email anyone a copy of my autoap file if you respond to the post. I did not log much other than fuel and igniton things..so its not much to look at. Thanks
