I just picked up a 2007 LTZ and the motor idles rough, sometimes it stalls and it sounds like it has a small knock sometimes. The only two codes coming up are 0030 and 0050, both o2 sensors. I can post a video if need be. I know my old grand Cherokee with the v8(31:cool: did the same thing when the o2 sensors were gone. But I figured I’d ask the avalanche club first lol.

thanks in advance..
 
A couple guys I know that know the truck said they think the lifters are stuck.. from the fuel management system. Anyone else have this problem?
