I have a 2001 WS6 TRANSAM. Just had code read. P0131, P0151, P0137, P0157. Both converters were changed at around 12000 miles. The car has been running a little funny for awhile. A couple of months ago it seemed to have a pre-detonation sound at full throtle starting at about 4500 rpm. It seemed to go away. then it started to run a little funky at part throtle. so i gave it a hard full throtle run. halfway through the run the ses light came on. thanks for any ideas.
