Q's for Tuners or Ford Techs

[01Steeda]

I have that issue as well. My O2's dont heat fast enough. I gotta bring my rpm's up a touch to get them heated when I start the car... didnt know it would cause you these issues though.

If it really is the o2's cooling off at idle, then you have a few options. Wrap the headers, have the tuner change the adaptive table to not apply or read at idle value, or force it to stay in open loop at idle. I've seen many guys resort to the last after getting tired ot fighting long tubes in their tune.

I think the latter is how we fixed it.

I would try some header wrap.. one of the reasons long tubes have this problem is because your LT's don't retain heat as well as the much thicker stock manifolds. Plus the placement of the 02's in LT's don't help..

This is why you see thicker headers/manifolds on turbo cars, it's because of the heat loss..

I think these guys got the answer here for your problem.. now it's just a matter of what method you use to fix it.
