Dear,
I am driving mustang 2005 with a built engine lvernoise 298 CI with a turbo kit, I am pushing about 12 PSI of boost, when I hit the gas the car performs very well but when I release the pedal the fuel goes rich almost 11.2 and again when I press the pedal the car gets back to normal.
Please guys support me since I don't want to keep on losing my spark plugs.
Regards
