Need Help

[ONE BAD EXCURSION]

Had my truck on A/E this weekend. Contribution low on #3, 1211 code and the one that puzzels me is the icp. The truck idles like it has a cam up and down. The icp reads 690 when it idles up and 630 when the idle down. Any help will be greatly appreciated.

Sounds like you need a black CPS! Love the Avatar by the way!

It is a steady up & down. Thing is it does not do it when the chip is in stock tune.

Is stock position the only position where it doesn't lope? How long have you had the chip?

[ONE BAD EXCURSION]

Stock is the only position that does not do it. I have had it about 1 year.

I would have to lean towards a problem with the chip. Will it set the code with the chip in stock tune or disconnected completely?

Contribution low #3 is the only thing I get in stock.

Excuse my ignorance but who makes the T/S chip? I would call them and explain your problem. Those guys usually have real good support. I think you have 2 problems, 1 being a bad chip and the other a bad UVC connection or bad #3 injector.
