Stock B16 running VERY rich
Just had my B16A2 powered civic on the dyno today and the AFR is way off, its 12 to 1 all the other B16's were something like 13/14 to 1.
It has Intake, and no cat, but thats all, the fuelling is effecting the power big time any ideas? Car and engine are 92-95, it has the obd1 ecu. When I took the plugs out last night they were black with a hint of grey on the tip. 2 Months ago the plugs were burning perfect. I thought something was up but not as bad as it is!
PLEASE can someone advise what to do, I was told it could be a sensor or something, although no codes are showing.
Thanks

Plugs were fitted same day, correctly gapped, cap and rota are a year and 8000 mile old, god only knows how old the 02 sensor is, Ive had it 3 years and never changed it, all fuel system is stock, injectors, pump, regulator etc.
Injectors have been recently cleaned.
Timing is set at stock.
