The test pipes have extenders on them already. The code is coming from the o2 sensors in the manifolds, not the TP. I wish it was that simple haha.
Llyod, thanks for the offer. I'll let you know if I can stop by this weekend. I sprayed the mafs with brake clean but the codes came back. I am going to take the whole intake system apart to see if I can find any leaks or perhaps a hole that has rubbed through.
