Hi all,

Here was my reading

NO ppm - limit 757
reading 1107 (fail)

Where to start. The car could use new plugs possiby wires and a throttle body cleaning, and a cap a rotor. I did notice slight hesitations while accelerating. After this if it still fails would it be the CAT. Thanks for your help

Check for any vacuum leaks (ie. holes/cracks in the intake tubes after the AMM which will allow more air to be sucked in resulting in a lean condition and hesitation.)

I did notice a hole in the air intake hose after the AMM just before the throttle body. Could this be it

thanks
