Awhile back i went to the track and had a dead miss and my a/f readings was going crazy. Ok i fixed the dead miss and changed the the IAC because its was screwing up at the same time. Well now after changing all 8 plugs TR6's gapped at 34 and the IAC my a/f readings are not was what they were before i changed them. Before i did the tune up my a/f readings would stay around 11.9 to 12.1 all the way thru the gears. Now when i nail it it starts at 12.1 and climbs up to 14.1, by that time i'm getting out of the throttle. As soon as it shifts the reading goes straight to 12.1. I'm running my warm summer tune. I'm not showing any codes. Could my 02 sensors be bad? Should i try to run some type of additive like toulene thru the motor and try to clean the sensors off? I have well over 200 1/4 mile passes on them all with race fuel. I hate to drive 4 1/2 hours one way to my tuner to find out its something that i can fix myself. Any sugestions?
