Car: 87 Daytona 2.5L TBI
It seems like my car is running a little rich. When I start the vehicle the exhaust seems to smell a little like raw fuel and I've noticed that the fuel gauge moves a little faster than I think it should. My odometer doesn't work so I can't calculate fuel mileage, but it seems like the car is running rich. It also seems to misfire at idle a little bit when cold but smooths out very nicely once it's at operating temp. The timing is dead on at 12 degrees, fresh plugs, wires, cap, rotor, HEP, and coil within ~1000 miles.
Could an oxygen sensor cause the car to run rich if it was on its way out? How do I test for this? I pulled the codes this morning and didn't see anything out of the ordinary.
