So the other day I fixed a large boost leak from the throttle body and my car started running very lean. My A/F gauge reads 18.0 and off the charts at WOT and 16.5- 17.0 at idle. I couldn’t figure out what was making it run lean and so I loosened the TB to make a boost leak so I could see if that was the problem. And with a boost leak the car runs perfect. I think the previous owner tuned the car with a boost leak. Any suggestions on what it could be or how I can fix it?
