I am throwing codes...

[SilverBullet00]

Since the LT install I have been throwing two codes back and fourth, the p0133 and the p0153 -Bank 1 / 2, sensor 1 slow circuit response. Is there anything I can do to help this situation, or am I going to need a tune?

That means that your 02 sensors arnt seeing enough heat when you first fire it up.

A. make sure the wire length on your 02s is as short as possable

B. You will need a tuner to adjust your cold startup procedure.

Tim had mine set to fire up @ like 1700RPMs and then over the course of a minute work its way down. (now with the shorter turbo headers he put it back to about like stock) .

But even now and back when I had LTs, if I took off driving before I let the 02s warm up fully, I had my hands FULL with the car. It wanted to buck and jerk very bad and would miss like crazy like it was hiting on 6 cyclinders at anything under around 2000RPM...and that would last for about a 1/2 mile (at low speed before I got to the highway) and then it would be fine.

But if I just let it warm up for about 30 seconds its usually fine.

One thing you may be able to do for now is after it cranks, rev it to around 2000RPM and hold it there for about 20 seconds....should fix it.

well the kooks came with 02 extensions, I might shorten them next time I am under there. I always let me car warm up for ~1 minute or so before I drive it. I guess I will see if revving it around 2000 helps.

It could either be that tha O2's are just old....I.E. slower than normal or the tune could fix it...........If the O2's are working try the tune first...........
