1995 m42 engine problems

Symptoms:

Fault Codes 1226 and 1222 are showing up
Cruise I get a CEL and its 1222 and if I give it gas it's go's away air/fuel showing rich mixture when this happens
hesitation from idle for a split second
split second power loss rarely while in cruise or under light accleration almost as if the computer is retarding the spark prematurely
Car will die on a warm start unless I give it some gas and help it out it will catch the correct idle



Looked over and cleaned:


ICV
AFM
No Vac Leaks
fuel presure regulator holding
replaced 02 sensor twice in a week

IM lost!! Im not sure if the 1226 is being thrown because the computer see's knocking or because the sensor is bad ... I dont hear any knocking though and this problem is geting anoying... any imput would be fantastic
