I have a 97 Turbo prelude. Since the recent temperature change, the lude has began to run lean, and hesitate. The idle at red lights and stop signs is completely gone. The car just won't idle once it's warmed up.
Could the problem be related to a bad O2 sensor on my AEM Wideband? I know it's linked into the p72 ecu. So could it have just gone bad and it's time to replace it?
Or any other help would be great. The car was running great since it was tuned about 7K miles ago.

Anyone - any ideas? I'd like to have the problem fixed before anything else go's wrong

 

Either the WBo2, bad FITV, or has idle fuel pressure issues with the large pump. I'm assuming the 68mm TB has provisions for the FITV? If not, that is probably the issue. I'd assume its a bad WBo2 that runs off the maps when cold - maps tuned while warm and FITV closed. That would create the lean condition.

 

what exactly is a WBo2?
