UPDATE ON YOTA: mass air sensor was bad. I just got it back home and its runnin good.........for now......I think the CAT might be stopped up it still seems to be lacking a little power. Thats as easy enough fix since we dont have emissions in this county. Im gonna cut off the CAT and put a new muffler and pipe on it. Any suggestions for a muffler on a 3.0 yota?
