formula1vhr2

Yesterday I noticed the engine running a little rough, then the CEL came on. Today started the car and heard a clicking sound coming from the engine. Parked it and pulled the following codes:

16805-Warm up catalyst: Bank 1 efficiency below threshold:P0421 00100001 01 Upper limits exceded,sporadic

17548- Oxygen (Lambda) Sensor:B2 S2: Internal Resistance too High: P1140
00101000 08 Inplausible Signal, Sporadic

16409- Bank 2:Camshaft B (Exhaust) Advance Setpoint not reached (over-retarded): P0025 11100010 02 Lower limit exceded, static, MIL on

17927- Camshaft Adjustmint: Bank 1 Malfunction: P1519 01101000 08 Implausible Signal, static

16684- Random/Multiple Cylinder Misfire Detected:P0300 01100010 02 lower limits exceded, static

16690-cylinder 6 misfire detected P0306 01100010 02 lower limit exceeded, static

16689- Cylinder 5 Misfire Detected P0305 01100010 02 lower limit exceded static

thoughts?

i would clear codes and swap coils around to see if misfire codes change

if the cam ajust chain or timing belt were broken , i.e. the car would not run.

the VVT is acting up, most likely the cause of the misfires. Might need a new VVT solenoid = $$$$.
