Diagnostic Code?
 

Check Eng.Light On. It actually come on and goes off randomly during normal driving conditions.
DIAGNOSIS:
Using a paper clip to bridge the E1 and TE1 ports on the diagnostic box under the hood, then turning key on but not starting car, I get the Check Eng Light to flash 2x then 5x.{ __^^___^^^^^___}
Does anyone have a factory manual that can tell me what code this is and what to do to fix it.
I recently had my Catalytic Converters replaced so I feel this may have something to do with O2 sensors but not sure.
Let me know thanks
