Odd check engine light?

[PMD Power]

My check enigne light coem on for only about a second or two then goes back off ans stays off while driving... it happend first after a long night of driving ( 45 mins of city) now it does it about 15 mins of driving. I check the codes and I get code 41 I know the O2's should be changed ( 157K on the stock ones) but what else should be checked? I did a search and I see allot of "check for vaccum leaks" but where should I be checking for these leaks? where do I need to start?

TIA!

Change out your O2 sensors. The light will come on if the PCM isn't seeing what it likes on that O2 sensor. Since it's only indicate 1 bank lean, I doubt you have any vacuum leaks. Replace and then see if you get any more CE lights.

I guess I will get on replacing them.. I just thought it was odd it would only be on for a second and be off the rest of the time... The zone has them for 40 bucks a pop... off I go...


Thanks!
