I'm thinking it is the one by the firewall that is in the exhaust manafold but not sure plz help

The bank 1 upstream O2 sensor is the one you can see when you open the hood. It's the easiest to replace. Hopefully, replacing the sensor will cure the problem. If not, then you've got a wiring problem, but a bad sensor is the most likely culprit.

My 2.5 (1997) has 4-O2 sensors. Bank one comes from the front of the engine, Bank 2 the back. Each has 2 sensors in them before they join together and head to the converter. The one toward the cylinder head is the upstream in each. The downstream is about 18" toward the converter in each. Therefore, Upstream bank 1 should be the first one you trace coming out of your front 3 cylinders.
