Truck seems to idle fine, but the more you drive it the worse it runs. Service engine soon light appears when engine reaches normal operating temperature. I have replaced spark plugs (with OEM plugs), plug wires, distributor cap, distributor rotor, fuel filter, air filter, thermostat (was stuck open), inspected all vacuum hoses, thoroughly cleaned throttle body and checked for water in the fuel tank. I am stumped can you please give me some insight as to what my problem may be?
