93 ranger 3.0 will throttle up with the air cleaner disconnected but will not connected have changed flow sensor air cleaner is clean tube from throttle body is clean. have not run across this before any ideas do the housing that the flow sensor fit in go bad in some way as to prevent flow or should I look else where crank case breathing or electronis. exray code reader does collant temp sensor not in range any bearing on intake.
