Closed loop AFR
Hello fellow members. I am currently experiencing some issue with my evo x.
Full bolt on with 1200cc and dw65c pump on E85. Tuned on Cobb by Doug @dbw motorsport
In Georgia.
Recently been having problem with my closed loop afr. Open loop afr are fine. While idling and cruising the afr tends to stay rich around 12.0 range before trying to lean out. Also it will sometime fluctuate randomly.
Have already check vacuum lines and all are accounted for. What else could I check to determine the issue. Could a bad pcv valve cause this. To much oil blowby.
