I installed a new 02 Sensor, now i get trouble code 44, 1993 Isuzu pickup 2.3.

(1994 Isuzu Pickup)
Could it be the new senor. Installed new sensor because the 02 Light was on. Code means 02S Lean, fuel metering (9) Please advise
What seems to make the problem better or worse? Drove truck 15 miles yesterday, light came on after mile 3.
How long have you had this problem? Since new 02 Sensor was installed

Multiple issues can cause a lean fuel condition - vacuum leak is the most likely.

However TESTING is always the key to a successful repair.
