O2 Sensor Problems I Guess?
O2 Sensor Problems I Guess? Car sputters on the highway bad 
.... Went and got the code and its PO155. Says its a "02 Sensor Heater Circuit Malfunction". Also says "Bank 2, Sensor 1". What is "bank 2, sensor 1"? Thanks.

Sure does... Would that cause the car to sputter real bad? Thought it was the fuel filter. Had that changed in K.S. Missouri on my way to MN where i am now. Did it real bad last night. It will rev up fine but put it in gear and go on the highway it does it everynow and then.

I guess ill have to get my other two 02's sent up from TX. Just moved up to MN for a descent job offer. I have the extra two post 02's, they should work for the front right?

I intermittently have been getting the 155 code for about 6 months. Should not affect performance AFAIK. Still a PITA having to reset the light, though. BTW, I've logged the O2s at cruise and at WOT and they seem to be performing normally.
