2002 escape 3.0 idle fluctuates and misfires when driving


No such thing as a tune-up

All you did was replace spark plugs which should be
done every 3 years

Oxygen Sensors get replaced at 100,000 miles which you
also did

You most likely have an intake gasket leak,smoke test
the entire Evap System & Engine

You also are have bad igniton coils

98 ford explorer high idle


Its either a faulty idle air control valve or a faulty fuel pressure regulator.My bet would be the idle air control valve. If you pull the vacuum hose off the fuel regulator or the map sensor and fuel runs out then the regulator is bad.If you replace the control valve then you have to reset the computer.

Failing NJ State Inspection for Low Idle emissions. Have replaced, EGR Valve, EGR selonoid, O2 Sensor, Idle Air Control Valve, Spark Plugs, Plug Wires, distributor cap & rotor, all vacuum hoses...


Catalytic converter. It heats up and burns off unburned fuel, if it's original, it's probably worn out. Cheap ones are not the answer.

Fault codes, p0102,p0122,po507


po102--maf sensor, could be a bad air cleaner and not letting air into engine, po122--tps pedal position sensor low, replace or adjust tps sensor,or wiring,po507--idle control system high input. for this you can take off idle air control, and clean out carbon from were it mounts on engine. it is just before throttle body at end of air intake hose, it is black. do not push on pintle on end of valve when cleaning, use a old toothbrush to clean carbon off of valve, use carb cleaner but do not soak valve in liquid of any kind. good luck!!
