So I bought myself a 07 h3 3.7 a week ago started to get p0171lean code 30 miles down the rd. Hooked up code reader was looking at readings and saw that the short fuel trim was running at 32% so read some post watch some vids changed the man. Sensor thought it worked hot down rd. And came on again changed the plugs sane thing so did some more research and changed the map. Sensor and pigtail thought it was good was driving it today and same thing p0171 lean code but then I got a o2 Sensor code today to bank 1 Sensor 1 still trying figure out witch one it is is it the one on exhaust manifold or the one before cat or after also changed the airfilter and the hose under resonator did a smoke test to check for leaks and nothing cleaned tb also with tb cleaner it does seem to have a slight miss but unplugged one coil at a time and all cylinders are firing so any ideas would be appreciated thanks in advance
