Contour Enthusiasts Group Archives Forums Modifications Duratec Maintenance Couple of questions.....

I plan on rebuilding my intake soon, and I was wondering how much of an improvement bigger injectors were. Would it be worth doing while I was in there, or am I better off just cleaning the ones I have?

Second, the O2 sensor behind the cat is throwing a code. I have a sensor for the front bank - will that one work down there, or are they completely different? Any help is appreciated.

BTW, search is down right now (just covering my arse).

Are you FI'd?....If not, don't worry about different sized injectors. The o2 sensors should be the same, but don't quote me on that.

If you put bigger injectors in I believe you will want to recalibrate the air fuel curve for the PCM. There are 2 sensors for each bank and they can be swapped between banks, but I'm not sure about swapping an upstream with a downstream on the same bank. I think they are different part #s. What code did you have?
