So lets fix this thing. Do the mixture test as I told you and tell me the results.

Do you understand how to change the mixture? (fuel/air)?

Your car is a 350SE and the motor is a 3.5l

The only thing I can tell you about the other group of numbers is the 876G is the paint code for Glasurit paint.
