    Does my MAP sensor look normal? Also rich idle. MAP sensor readings seem reversed?

    Ok ive got the car to idle. AFR's are 11-13 at idle. I have changed everything I can think of with no change. Here is my last log with the current tune. any advise is appreciated. my map at idle is 70 to 80 which is why I think its rich. It seems like its reversed.

    Have you checked for a big vacuum leak?
    Your MAP is working. It makes it to 40kpa on decal, but it should approach 20 there.

    The o2 sensor problem I believe is an exhaust leak I'm going to fix that today. I will also check for vaccum leaks thanks for the replies.
