2002 ford crown victoria 4.6l v8 engine stumbles when under load
i have a 2002 crown victoria police intercepter with a 4.6L V8 and it has been stumbling under load. when it idles it is fine does not misfire or shake but when i try to drive i lose power, it stumbles and shakes very bad i have checked almost everything.
ive checked plugs, coils, fuel filter, fuel injectors, drivers side catalytic converter and o2 sensors, air filter, intakes,
the check engine light is not coming on and when it does and i hook reader up to car it powers up but will not take the codes from car
