Can somebody have a look at this tune for me please???
The car is running rich at idle and light throttle. The scanner says it's in Closed Loop - Normal, but the O2's are reading over 950mv and the Trims are at zero.
As soon as the MAP gets over 50kpa, the trims work perfectly and the O2's start swinging as they should. When the MAP drops back below 50, the trims go to zero again...
HELP?!?!?!?
