Ur-q timing belt.

Q-list,

Finally got the computer side to work properly (sort of).
However I had some problems with the CO setting.
I used the FV duty cycle to adjust CO and would get nice 35-45%. It has
new Oxygen sensor and full tune-up.
However it was fluctuating a lot and the car would back fire as soon as
some throttle was given.
I thought since all the sensors and computer looks to be in the right
order I will check the ignition distributor position.
I put the engine at TDC and found the distributor at the correct basic
factory setting.
However I found the camshaft to be off by one tooth (you have to crank
the engine ~one tooth to see the mark lign up with the cyl head).
I removed the the T-belt cover and found rubber shreded dust all over.
Looks like original T-belt with 130k on it.
Question is:  would camshaft advanced by one tooth couse this poor
running?
I remember someone mentioned the possibility of moving the T-belt
setting by one tooth without major effects on engine performance.

BTW a new belt is on it's way in.
TIA
