Ok, i had my megan mids and tanabe installed by a local shop alittle over a month ago. Yesterday my check engine, red triangle and VSC lights came on. Went to my lexus dealer and they came up with four codes. They are:
P0113-states, intake temp curcut(spelling on the sheet)?
P0102-states, mass air malfunction
P0158-states, O2 Bane 2, cut O2 wires (can't read the tech's writing again)
P0606-states, ecm/pcm processor, exhaust leak and cut wires

Can anyone confirm/correct these? I sent an email to the shop owner with an attached pdf of the tech's inspection sheet. They better fix this or i'm going to be pissed! The tech said that they cut the O2 sensor wires and reconnected them but didn't do it right.

sorry for the long post just frustrated! thank you to anyone that can help.

why did the local tech shop cut the O2 sensor wires?

 

Don't ever go back to this shop again.

when i came to pick the car up, they said they couldn't get the o2 sensor out of the stock exhaust due to rust or something. they said they had to cut the wires and ordered a new o2 sensor. i talked to the shop owner and he asked me to bring the car in next monday. should i see if they can fix their mistake or take it to another shop? He said he will fix it with no problem. i'm still alittle cautious. thoughts?

 

They should have used the right tools for the job without cutting anything. really sad when the SHOP is doing this.
I did the JoeZ exhaust installation using the right O2 wrench free renting from Autozone.
Hope you got it fixed soon. GL!

 

i agree with the following post.

here's why.

my guess is that the local shop didn't have the right O2 sensor removal tool, so they cut the O2 sensor wire to facilitate removal and figured they could splice the wires back together later. the splice job might have been mickey-mouse'd, leading to the issues w/ your 2is. in addition, they might have not re-installed the O2 sensor properly, causing your 2is to throw those codes.

again, as javyLSU has recommended, do NOT go back to that shop. tell them you'll take it to an authorized lexus service center, and that you'll be forwarding your bill to them for reimbursement.

hope you get your situation resolved. keep us updated.

 

Dont ever go back there you was better off DIY.

 

Wow that's crazy. Bet they will never do that again when they get the bill from Lexus

 

What kind of Lexus dealer is that? No o2 socket? Whats cutting the wire hafta do with taking the sensor out?

Report that dealership to BAR.

 

uh... it's the OP's local speed shop that cut the O2 sensor wire, not an authorized lexus service center.

reading is fundamental.

 

ok, so i talked to another member here and he had some work done at this same shop. he said that they fixed an issue with his GS doing throw some codes from an exhaust too. the messed up thing is today i go to lunch and start my car and no warning lights!!!! this happened a couple weeks ago when the lights came on then after my car sat for a couple hours nothing. is this normal? i'm still going to have the exhaust checked but wasn't sure what's going on. any ideas?

 

if it was installed correctly, then it should not be erratically throwing error codes.

assuming that it's not an issue arising from the mid pipe's design/manufacturing, my guess is that the shop that installed your midpipes did not correctly re-install the O2 sensor into the bung, causing a visibly undetectable exhaust leak.

that, or the shop's cut-and-resplice wiring job is not holding up.

regardless, i still stand by the recommendations of NOT going back to that shop.
