Isuzu Rodeo 3.1, TBI. Noticed an injector was pissing, so I replaced both with new ones. It runs better now, but the condition is still indicated. O2 sensor was about 6 months old, but I replaced it anyway. No good. New air cleaner, new spark plugs, cap, rotor, and wires. Can't find any vac leaks. Any ideas? It runs fine, but the guy down at the inspection station says any codes must be negated for it to pass emisions.

straight out of the haynes manual
Check the wiring and connectors form the oxygen sensor to the ECM. Check the ECM ground terminal. Check for a sticking M/C solenoid. Check the fuel pressure. Check for vacuum leaks at the carburetor base gasket; throttle body gasket, vacuum hoses or intake manifold gasket. Replace the oxygen sensor
