The non foulers did not work I think due to the distance of the cel fix that came on the test pipes and then with the extra cel fix I put on. They might work better on a 03-06. I'll get all the info on them for you guys. I know a lot of people are asking about them. I'll try to get more vids up this weekend. Thanks for all the comments.

 

I think my o2 sensors were seized as well. I have Berk's HFCs. My car sputters around 2500 rpms. Do you have that as well?

 

^^I have BErk HFC and my car is fine right now

 

It studders when I floor it under 3K. Once I get past that it pulls hard. ???? I'm going to look over the intakes again and make sure nothing is loose. I'm going to get longer breather hoses too. We'll see what happens.

 

UPDATES!!!!!!

Just got the new factory lower o2 sensors installed and guess what?

NO MORE STUDDERING!

Just to make sure I drove in every gears under 3K and went WOT and no hesitation. I'm glad that this problem is finally fixed. Thanks to all that have helped out.

I still have a CEL but no biggie. Alls good!

Hey guys I have a pair of Bosch o2 sensors with spliced wires to connect to an 07 Z. You can also use them for the 03-06 but you have to use your stock connectors and splice them together. Here's some pics. I'm asking $125 shipped. I paid $115.00 each plus shipping. They have less than 1K miles on them.
