Hiccup before pump1...
 

Whenever I rev the car there is a hiccup as it leaves idle and goes to load maps. The wideband goes all the way lean for a split second then back to 13 or whatever. It also does this when I am under almost no load or no load cruising and then hit the gas.

This happens before pump1 comes on. Is this problem because pump1 trig is set too high? I have tried to adjust but it doesnt seem to help. Right now my pump settings are all factory.

Any suggestions would be helpful.
