How often does that happen?
Mine seems real screwy, reading rich or lean when steady throttled. Going way lean at times for no apparent reason.

Where can I get the best deal on a replacement AEM sensor?

 

i bought mine from this guy.

I should have been more clear, my wideband O2 sensor is screwy. I have an AEM wideband and I think the sensor is f'd up!

 

no prob

 

Which set is going bad. If its the rear i would say save a couple bucks and just buy simulaters, i hooked up with a pair that went right in the oem connecter with no spliceing for under $80 total. I pulled the cats on my truck when i did the dual exhaust and they work just as good. I pop up with a high voltage every once in a while but it clears off in that same day. Plus the rears dont do much more then tell u how well ur cats are working so they have no real effect on how the vehicle runs. just a thought

 

I don't have rear O2's LOL. I messed this post up!!

I have the AEM wideband UEGO controller and I believe the sensor is whack. How many Wideband users have had to replace their sensors?

 

My WB is an LC-1 and it crapped out a couple of weeks ago. Symptoms same as yours. Don't know if AEMs need this but the LC-1 needs a free-air calc every few weeks. You may also want to try that. Otherwise, I got my replacement sensor from Dynotune.

 

I just ordered a new AEM sensor from Summit $75 . Nothing on their (AEM's) website about free air calc....Hmm.

 

speed density tune..then you dont have to worry bout o2's or if your pegging your maf out

 

LOL
One more time...

I have a SD 2-Bar tune with MAF enabled and Meth Injection. The Wideband is used for monitoring and tuning. The PCM does not use my wideband data.
