Question about my AFRs.. So on the highway after WOT i take my foot completely off the gas and my wideband used to go --- now it sweeps.. Is this an indication of a leak? Or TB issue? Or is this just normal. Here is a quick video.. Make sense?

 

is there a way to recalibrate your sensor. iv read that some ppl have to do this everyonce in a while. also idk remember where but it was on youtube on how to test if your sensor is actually bad. might check it out. is your car tuned?

also are u running a vta bov or is it recirc. if your vta that miight be your prob. its just letting ur car run reallly rich when u vent that to atmosphere. makes sence cus if your too righ to be read by the gauge then it will read-- out of range..

hope ya figure it out.

 

I have seen the video test on how to test the sensor.. I have a synapse BOV but I have it recirc. This did start when I changed the BOV.. So that could be the issue. I have not retuned the car since I changed the BOV. I am planning on hitting the dyno to do some tuning so maybe that will resolve some of the issue. Thanks for the reply.

 

no prob thats what we are alll here for lmao ,p hope ya get it worked out
