Help with a CEL code: P1128
For some reason, my car keeps throwing the Code P1128 which is like MAP sensor voltage lower than expected or something. I am Running the Greddy E-manage for my turbo setup for the time being. I finally understand why a lot of people dont use this lol. Anyhow, What would be a probable cause for this CEL code?
When this CEL code is on, my car kinda bogs and it try to spool the turbo at low RPM's. If I go WOT, my turbo will fully spool, wastegate will open and hold steady boost, but the car pulls forward really slowly and feels like its choking. Any help to rid this problem would be great!. Thanks.
