ok,
on my way home today, and the "service engine soon" light beamed to life...."darn it".
got home, hooked up the old code reader and i got this code...

PO133
O2 Circuit
Slow Responce Bank 1, Sensor 1.
there was also a CL Fault in there..(what is that??)

what info do you guys have on this deal?? i plugged "PO133" into the search, but didnt come up with much.
i cleared the code, now im going to wait and see if the problem persists.....

Sounds to me like your front O2 sensor (just below the exhaust manifold) is fading and needs to be replaced http://geometroforum.com/topic/638390/1/#new Have younoticed any drop in fuel mileage? Not sure what a CL fault would be...

well,
i cleared the code last night and the "service engine soon" light has stayed off...so far. sensor is probably getting ready to fail, my gas mileage is normal, but this hiccup may be just the beginning......i may replace the sensor just for grins.
