my 99 e250 with 5.4 gas engine has 2 upstream sensors and 1 down stream sensor.
I have a '95 E150 and a '96 E250, both are 4.9 straight 6 cyl. One has 1 O2 sensor and the other has 2, one on each half of the exhayst manifold. I believe the 96 has 2. but it is an E250, not sure about the '96 E150.
How many oxygen sensor on your 1999 3.5 rl?
an o2 sensor is the same as an oxygen sensor. vehicles can have up to 4
