Less is Better
My point with the OBD2 reader is to watch the behavior of the sensors, not to look at codes. You need further diagnostics and the beauty of OBD2 is that you watch how the car is working.Me and my mechanic hooked up a preassure gauge into the fuel line, and took the car for a drive, while checking it, and according to the mechanic it is all good, it also deliveres the right amount of fuel that is should. He also have had his diagnostic tool with him in the car, while we where out driving, but the only codes we get is "P0171 powertrain too lean bank 1, and P0172 powertrain to rich bank 1"
When i accelerate between 2000-4500rpm, it feels like the car is drowning in fuel, but if i let off, just slightly it comes bac to life, and when it passes 4500rpm it is fine. It is the same int the 2000-4500rpm range, either i am doing 30kp/h in 2. gear or 130kp/h in 6. gear.
