ok...so have had an SES light forever now.. car runs a little funny low end tq is lacking most of the time...but seems if the car is driven hard it runs better (doesnt lag as much) but anyway i have several codes and have replaced these with NEW OEM: cam POS sensors..... BOTH valve timing solenoids. May I mention my car has 166,000 miles on it, and I replaced the engine with another 04 max engine that had ~50k on it, and ever since have had this problem, i have these check engine codes:

P0011 - IMTAKE CAM POSITION TIMING - OVER ADVANCED BANK 1 <br>
0021 - INTAKE CAM POSITION TIMING - OVER ADVANCED BANK 2 <br>
P1135 - INTAKE VALVE TIMING CONTROL CIRCUIT - BANK 2 <br>
P1110 - INTAKE VALVE TIMING CONTROL SOLENOID <br>
P1283 - a/f sensor
