I own a 1996 gmc sonoma with a 2.2 engine. I got a code of p0171-1 lean bank telling that it was the MAF sensor,it doesn't have a MAF it has a MAP sensor so i changed it. It drove OK for a few minutes then when i got a warn engine it started service engine light came on and i got the same code. What else can i look for to slove this problem?
