I have a 1997 Land Cruiser, TRD Supercharged, with 107, 000 miles on the clock. A couple of years ago, prior to adding the Supercharger, the check engine light would come on occassionally. It was setting O2 senor codes so I replaced both sensors with new OEMs. The light stayed off up until a couple of weeks ago now the light is on and it is setting sensor codes again. I have noticed zero drivablity problems. Seems like the O2 sensors should last a bit longer than 20,000 miles. Can anyone advise if they have had this difficulty as well? By the way, I am also running a Borla exhaust. Thanks.

Supercharger, sweet! The only way to fix it is to drive it up here to Holland and swap it for my stock '97 with new O2 sensors. Or drive it up here, and we can plug my laptop into your OBDII port and look at codes and sensors and stuff.
Check the connections on your plugs. How are your cats?

My mistake, I'm not getting an O2 sensor code I'm getting the dreaded P0401 EGR code. I see a lot of post regarding that code. I guess I'll have to do some digging as it appears there is not a common issue with any certain part.
