Installed my 703 injectors last night. After a few miles down the road, my CEL came on.
I am getting code 51 ODBI:
51 Oxygen sensor stuck at lean position (this may be tripped by a bad MAP sensor system causing a rich condition. If you get hot rough idle and stalling, especially on deceleration, accompanied by flooded engine and difficulty restarting, that can be a bad MAP sensor causing the O2 sensor to try to compensate. If you get poor cold drive-ability, stumbling and bucking, and acceptable warm driving with poor gas mileage (a drop of 10 mpg or more), that is usually the O2 sensor.
OR
51 Internal logic module fault ('84 turbo only)
Obviously not the latter. But I am getting none of the symptoms listed above, on the contrary, it seems to be running well, but I CAN tell a difference in exhaust odors.
Can someone help me understand? Do I need a new o2 sensor? Is this common after this upgrade?
Thanks
