---sorry i posted this in the wrong place I think.--- I am working on a 2001 aztek for a friend of mine that is is need of her car repaired and doesnt have the money for a shop. This car will start up kind of hard for the first start, then drives maybe a mile or so the stumbles back fires and stalls. I can start it up right away after it stalls no wait at all then it will drive a short distance like a 100 yards or so then die again. hit it with a scan tool and pulled these, ready for a list:: po741, po125, po130, po133, po138, po141, po171, po172, po401, po420, po440, po442, po446, po530, p1133, p1134, p1441, p1554, p1860, 1887. where should i start. the gm factory book always has a code listed that isnt suppose to be present for every diagnostic sequence that is listed. any ideas???
