Hey All, I have a 2008 GT race car that runs great for the first 10-15 minutes than struggles to get above 4,000 RPM, it feels as if the car is starving for fuel like it wants to rev higher . Sometimes there is no CEL, other times it throws code 358; engine scan reveals no abnormalities. I have replaced all 8 coils, the injector on #8 cylinder, the throttle body, the fuel pressure sensor, the fuel pump, the fuel filter and all 8 spark plugs. The car is running headers with no cats.
I am at a loss, I was going to try engine wiring harness next and then ECU.
Anyone have similar experiences?
thx,
Ray
