intermittent wideband

[LETZRIDE]

So for the past 2 days my wideband has all of a sudden gone wacky on me. It seems to be reading between 10-12 afr all of a sudden, while the narrow bands seem to stay up at 700-800mv, which tells me I am not in the 10-12 afr range. Then all of a sudden the wideband will read fine again, then not, then fine, then not...what do you think can cause this? It is an AEM UEGO wideband that is not even 2 months old...Please don't tell me I just puked out another wideband...I just finished eatting 2 LC1's prior to this AEM...

Re: intermittent wideband

If it is bad just go with a PLX, I have had mine for about 9 years with no problems, knock on wood.LOL

Re: intermittent wideband

AEM was supposed to be good...I don't want to go through yet another wideband...in less then 2 years I will almost have bought enough widebands for individual cylinder tuning, but still not of been able to do it...

Re: intermittent wideband

PLX all the way, I'm still on the same wideband sensor also , so I have got my moneys worth out of my wideband, plus Hptuners has the PID for it and it is easy to get it right on the money.

Re: intermittent wideband

im wondering if the fact that I am burning oil is killing the sensors on me...

Re: intermittent wideband

If you burning oil or running too rich your sensors are going to be shot.

Re: intermittent wideband

there isn't really a way for me to stop burning oil though...am I just totally screwed then? my narrowbands are stock with 240,000 km on them and they are still fine?

Re: intermittent wideband

The best thing you can do is mount it as vertically as possible. Just so junk doesn't sit around in the sensor. Have you tried installing it temporarily into the headers?

no, I got it in the stock location just before the cat...maybe I'll try a different spot, or I was thinking of adding an extension...

Re: intermittent wideband

You mean one of those heat sink deals? I need to look into something like that for myself.

ya, they usually use them for turbo cars I think...but killing widebands is getting very expensive...

Re: intermittent wideband

Q: How do I make a heat sink?

A: Take a 4-5” square piece of copper (optimal) or aluminum, and punch/drill a hole just big enough to fit over the threads of the O2 sensor. Bend it so that there are two “wings on either side of the sensor. Mount the heat fin between the sensor and the sensor washer. We recommend 0.0647" thickness 4" x 4". (Or you can buy the Innovate HBX-1).


Or the actual Innovative HBX-1 looks nice.. But expensive.

Re: intermittent wideband

Copper should work great, I could see if you were runnning a turbo to do it, but N/A just put a spark plug heat cover on it and be done. I would also make sure you CAT isn't clogged and causing your wideband to heat up too much and making it burn out, I don't run a CAT so I haven't had any problems like that. Or go with a PLX.:D

Re: intermittent wideband

cats brand new...that copper thing is ridiculously expensive...its basically just a copper washer...take a couple pennies and drill holes through em ...holy sh*t

Only if pennies were huge.. btw steve, I know what you're thinking. No.
