make sure you have the perameters set correctly in the vafc... then check your wiring. if you are adding too much fuel then that can cause the cel.

 

what you mean by parameters what settings

 

so youre saying if i set the fuel wayy too high ill throw a code

 

Make sure your sensor types are set to 6.

 

yeah they are at 6 in and 6 out

this is from adding too much fuel.....the vafc is telling the computer that the map signal is getting into an unacceptable range by the ecu's standards....you need to pull some fuel out there....then it will work fine, your wiring should be ok

edit: dont play around adding fuel without a wideband...you will wash down the cylinder walls and ruin your rings....

 

thank you very much peeps for helping me i will do that
