LT1-LT4 Modifications - I keep going through o2 sensors

Today I was going to take back my o2s and get 2 more, Im on my 3rd set and they said we cant give you anymore just refund your money Im useing bocsh ones. I have lts no catts and flowmaster catback computer is tuned at pcmforless why am I using so many o2s they are carboning up seems. Im going to try to gett some delcos anyone know anywhere to get a good price on them.

why do you pull them out? does the car run bad? if so what does it run like?
how do your plugs look? these are your pre cat o2s right?

I dunno where to get Delcos beside the dealer, but sparkplugs.com has densos which are also a very good sensor for a pretty good price. Do you seem to be running rich at all? Because that could definitely be an issue with the O2 sensors and some have had issues with Bosch on our cars.

Have you logged the O2 output? Are you getting "lazy" sine-waves instead of picket-fenses? Are you getting a code?

Where are the O2's located (in the collectors?)? Hopefully you didn't put them farther down stream. If they go too far back they'll get lazy signals no matter how hot you keep them. Do you have a pic?

the car was a v6 I put an LT1 in so I plug under the dash doesnt work to read codes. I ses light comes on sometimes it does run rich. the plugs dont look to bad.

yes the car only ever had 2 o2s before the cat never 1 after. when I change them the car runs good for a while.

What does your exhaust smell like?

you can get delco 02s from SPDC, or even RMS autoparts.com

The sentiment towards Bosch O2 sensors seems to be overwhelmingly negative. Get some delcos. I've never bought anything from gmpartsdirect. Their prices always seemed very reasonable until you get to checkout and they hit you with some astronomical shipping charges.

^^ Most times the shipping charges were just fine. I've compared prices with RMS to GMPD and GMPD came out like $3 cheaper in the end.

However if you want your stuff in a hurry, RMS or SPDC. GMPD takes at least 7 days to get your order collected and shipped.

It may depend on the part. The shipping and handling for an unvented opti is 80.21 at gmpartsdirect. That's crazy. An O2 appears to ship for 4.15. I think you could still do better.

thank you for the part number

19178930 new part number

yea I looked at gmpartsdirect they want 26 to ship to o2 sensors.

13111 Bosch Rear Vette 02's are what you want......25 months and PERFECTION. No codes or B.S.

interesting. I ordered a bunch of small stuff and they only charged me $7.00 SH. $13 each sensor shipping is fucked up. Not to mention $80 for an opti!

yea Ill tell you thats half of what each sensor cost

like I said there's also RMS autoparts (google them for complete addy as they're not a vendor on here) which has basically the same prices without the raping shipping.

One thing for sure is I miss Dal S.

I thought Dal was still around. I'm pretty sure that Jason C. is.

Dal has retired from the parts business. IIRC his email addy is still around, but he's not affliated with any business that sells parts anymore. He was working with RMS for a short period of time, but then retired.
