ran the koeo tests and got codes 172 and 176.. also ran the koer diag tests and got codes 172 136 129 and 167...... all of these seem to be related to the high altitude that I live at.. 6200 feet. it's a 95 with manual tranny... Any suggestions on what I can do to compensate for the thin air at this altitude, to make the engine run better or stronger ?? I also ran the check cylinder diags, and all are okay...
