Re: Small fuel mix problem
This has been on another forum where someone said that changing the fuel pressure regulator would change the A/F ratio?.
The fuel pressure is OK.
I will check the MAP when I think of someway to create a vacuum. Maybe a vacuum cleaner. The normal pulse rate is OK. Pulled a pressure gauge apart and moved the needle to make it read vacuum.
After lots of checks, now think it is most likely the fuel. Or a crack has appeared somewhere.
Or just wait and see if all returns to normal. Thought that the fuel may have been 'diluted' (ethanol?) and the computer has not adjusted.
