Hello
good night I have a problem with a blazer accelerates the P0171 code that corresponds to poor mixture in the number one cylinder. Already try several things such as:
- Change the acceleration body
- Verify if there were air jalones
- Change the multiple of admission
- change spark plugs and lave injection
- Reprog me the motor of the engine with the last update recommended.
The acceleration is 1000RPM. I no longer have ideas to solve this problem if they have suggestions I would thank you very much
