I know what it means but Im not sure what the fix is. I have checked the fuel pressure and all checks out. The pump runs fine on run. The book says its a open circuit to the ECA to motor ground. Anyone ever fix this problem. No check engine light but the car misses under boost. Has newer wires ,plugs,coil. I pulled plugs yesterday and they seem to black but not much carbon.
