O2 Sensors

No, that is not bad sensors causing that problem. It is your engine running too lean for some reason and that's what you need to find. Look at fuel pressure, vacuum leaks, MAF and other things that effect fuel pressure.

There are four, but re-scan as it should say which one it is probably the one before converter though. Make sure not air or vacuum leaks though as the manifold may still be leaking vacuum.

Especially as the intake was just replaced and then the light came on. I have seen new ones out of the box that were warped enough they did not seal.

A code P0141 may mean that one or more of the following has happened:

"� open or short to ground in the wiring harness
"� O2 heater circuit wiring high resistance
"� O2 heater element resistance is high
"� Internal short or open in the heater element

Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.

Possible Solutions
"� Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
"� Repair short or open or high resistance in wiring harness or harness connectors
