I had just finished my rebuild and im trying to get this engine to run properly. I have Weisco 8.8:1 pistons,Crower stage 2's turbo grind cams, Stock injectors, 255 walbro and S-AFC. Now for the first problem...what should the A/F for a wideband be at idile? My car acts normal while warming up but at soon as its warm, it leans out. Im not sure why this is happening at all. My wideband will read in 14.8 - 16's and its starting to bug me. I just want to know what some of you guys read on your widebands at idile.

Second problem...I have this retarted CEL. Its code P0106, Barometric Pressure Sensor (Rationality Check). I dont know if this is the MAP sensor or its something hard wired into the ECU. I was getting this code before the rebuild too. I have a missing link on my MAP sensor so i didnt think it was that. If someone could help me on this CEL...that would be great! I have read somewhere on here that this code means something about the MAP sensor, but im not positive.

I forgot to mention that there is no exhaust from the 3" DP and back leaving the back O2 just hanging there. Maybe that has something to do with my screwed up idile. Thanks for any help you can give me and sorry for the long post.

If it's a 97 or newer, probably. Fix that.
