The codes are coming from the top front sensor. Check it's wiring.

Check IMRC operation. Try a good fuel injector cleaner. Consider replacing the intake gaskets. Since they are O-rings, they can go bad with age.

The roughness is probably just from the extra fuel being used.

Thanks for your help in this matter,I can rule out the intake gaskets they are new from when I cleaned my secondarys over a year now.When you say the top front sensor are you ref:to the 02 because thats new has well, the cam sensor or the mass air sensor or the tps ? Can you clear this with me that sure would be a great help.
Today I replaced the throdel body gasket and fuel filer which were both need and cleared the codes only to have the same ones plus two new ones p0300 and p0174 come back and the car runs no diffrent...STill need you help.

Thanks R96SE

3 contours V-6 and all are throwing codes...sick of it..
replace o2 sensors,tried MIL eliminators and nothing
works...any comments on this B.S. that can help me...
I,am in the same boat with R96SE....

Well it turns out that one of the two new o2 sensors were bad, replace with new one and so far no new check e light and it is runing just fine .Thanks for your help with this.
