hi everyone. I have a 2003 Corolla that I had the tranny replaced on last year. Since that time I've had a check engine light and its throwing the same codes. P0171, p0300-0304. Isles rough and sometimes stalls when stopping. I've had several mechanics look at it and done some work and nothing helps. Saw in another forum that a mechanic crossed 2 vacuum lines during the instal and finally found it. This sounds like the only thing left that could be my problem. I have no more money for mechanics so I'm going to attempt with my dads help to find these lines and fix them. Anyone have a schematic by chance? Thanks!!
