Hi folks

Got me a dawes AFR meter fitted the other day and I'm getting funny readings, off boost it should do the knightrider thing when the lights go up and down so to speak, but they very rarely do and on full boost i'm getting no lights whatsoever ? I've watched it a couple of times when I've applied WOT and the lights go up to rich and then shoot back down to lean and then off !!

Could it be my Lamdba sensor is giving me dodgy readings ?? its only 4 months old and its not coming up when I do a ecu reset ?

Any help appreciated
Thanks

 

Problem solved folks it was the earth connection on the 02 sensor !!
