The O2 sensors were definitely the problem. Drove the car last night before I changed the sensors today. They really have a impact on fuel management. I thought the car was running OK but it wasn't. I stalled the car like a newb coming off a light, like I was in third. Acceleration seemed OK till I got off the throttle and it acted like the fuel shut off for a split second. Driving around town in fifth gear, car struggled to run, had to stay in third and fourth.

Got the car up on the ramps and swapped them out today. Cleared the codes and took it out for a run. Happy to report I'm back to running like new. It took longer to set the Race Ramps up and get the drop light out than it did to change them, very simple to do.

Carboned up pretty bad.

Good to hear you got it figured out John. So I'm guessing that these are the front O2's and now they are further downstream from the OE location with the LT's?

Could explain why they got carboned up that bad because of the relocation further down in the exhaust header collector vs. stock location.........................something to think about if you are considering going with LT's.

Hey Tony,,,

Yep, front O2's. For what I've gained with LT's, changing out a couple of sensors is no big deal. I won't go back to stock just to save the sensors. Not worth it to me.

Hhhhhmmm, I'm wondering if anyone else is having this problem with LT's. So how long did the first set last after you installed LT's John?

For some changing O2's every once in a while might be what's needed to run LT's so sensors stay fresh, but not sure if others (like myself) want to deal with the extra expense if they get carboned up that bad being relocated from the factory location.

Between 5-6K miles, $100-$120 a pair, a minute or so to change out, small price to pay to run LT's!!

After talking with a few guys, it is a minor issue with running LT's. They keep a spare set of sensors available to swap out when they start acting up. Nature of the beast with LT's. Like I said, small inconvenience to run LT's that I'm willing to deal with. Love my LT's!!

where did you get your O2 sensors at?

Bought mine from my dealer, $60 ea. my cost. Think you can find them cheaper other places. Just keeping my relationship in good standing with them, never know when you need them for bigger issues.

Do you think adding a washer or spacer to the o2 so they do not go in as far would help? Someone mentioned he needed a washer so the o2 is not so far in. Just wondering. I am stock but, will add Long tubes in the future. Do you have cats? Just wondering if I should go with cats or not. Thanks...Glad you found the problem...

Rock auto.com has them pretty cheap as well. I paid 45 for mines when I messed them up in some deep water.

Nope, no cats.

Not sure about the washer. They have one on there factory. Don't know about adding a second.

Glad you got it fixed

I keep 2 extra sets of O2's
It's a good idea if you are modded
But since I got the NTK O2's from advance auto parts
These seem to last longer

Removal all sensors

Detach the pin type retainer and disconnect the HO2S electrical connector.
NOTE: If necessary, lubricate the HO2S threads with penetrating and lock lubricant to aid in removal.

Using a crowfoot wrench, remove the HO2S .
  • Calculate the correct torque wrench setting for the following torque. Refer to the Torque Wrench Adapter Formulas in the Appendix.
  • To install, use a crowfoot wrench, tighten to 48 Nm (35 lb-ft).
To install, reverse the removal procedure.
  • Apply a light coat of anti-seize lubricant to the threads of the HO2S before installing.
