Heres the situation.
Rebuilt my motor.
Everythings running fine and dandy.
Turn on the car in the morning and go about my day and from a COLD start, the CEL comes on for just Code 1 and 16, once the car reaches Operating temperature. Come to a stop, shut off the motor, turn it back on again, now that its already at operating temperature. Never comes back until i do a cold start again. when the CEL coems on, theres no change to the motor what so ever. none of my cylinders go out. no wear idling, no backfirng or psuttering or rpm walls. really it doesnt effect me but its just one of those things that i would like to fix... ive taken out spark plug one by one and yeah it wants to die but it idles like a champ

Code 1 is OXYA and and Code 16 is fuel injection.
any ideas?
like i said, rebuilt the motor.
cleaned out all my sensors. theres no leaks of coolant, no oil leaks, not burning through any of it.
didnt do it before the rebuild.
ive got new..
spark plugs
wires
all new dizzy
new thermostat.
any help or suggestions would be great
