When my MAF is hooked up My car will not shift at WOT,Does not idle right in gear or in neutral.When I disconnect it the car idles perfect,shifts right on time and the car just seems to run better.The trans seems to shift harder though at low rpm,I have a shift kit.Can I leave it disconnected,If so what do I have to do besides turning off the check engine light.97 C5 H/C headers.And my wide band still does not seem to be working.When I plug it in it reads "rich" for a split second then "14.67" but does not change when I go for a drive,.And yes I have to be careful on WOT till I fix it.
