wrong o2 sensors?

[jmatt07]

i recenty finish h/c/i swap. put lontubes on and reconnected 02 sensors. the wierd thing is, is that i didnt need the o2 extensions bc they reached the ones that were closest. i also got mail order tune done but the has had the check engine light on since i started it. the codes that were pulled were P0134 and P0154....i think. anyway the codes were no reading from o2. did i hook the02 sensors up to wrong connection?

Considering the codes your throwing, did you connect the 02's to the front wiring harness or the rear 02 harness?. The harness you plug the sensors into should come from the front of the vehicle towards the engine, not next to the transmission.
I think you just connected them in the wrong spot.

I agree. You have them hooked up wrong. The front harness' drop down off the k-member.

ok yep thats what i did. i hooked em up to the ones by transmission bc i didnt even need extensions. with that and the fact that my pcv isnt really connected lol. i put half a tank in it and drove 70 miles and its bone dry
