The o2's both banks indicate lean , & idle is high?
Look for a vacuum leak your problem prolly lies there.
Also make sure maf is clean & no leaks in bellows etc.

thanks for the fast reply man, i think i might have a leak too, would a egr leak do it?

Yes , anything letting un-maf metered air in 'specially an egr tube.
You can use a hose to "hear " the leak, or spray carb cleaner at the spot & see if the motor reacts to it.

sweet thanks a ton guy, i found it, there s a hose leading into the manifold right after the sensor that melted, so that is prolly the problem, melted hoses are never good
thanks again for the quick replies -matt
