does everything look okay with the car in park at idle? car still has a hell of a time starting? changed out the ngk fouled plugs will try starting it again tomorrow see it the brand new plugs make a differnce. both the o2's go crazy with reading when the car is running- might be cause the bad plugs? or maybe the o2's are fouled also from it running to ric h with the 2 bar map?

also have a high flow maf sensor... thanks

Your best bet is to read Injuneers write up on scan readings, it is very informative and has helped me out many times. http://members.aol.com/InjuneerZZ/ScanMast.htm

Your block learns are maxed out and integrators way high. It's not really very useful to try to determine problems from snapshot values.

how will the learn values and the intergretors hurt my performance? car has yet to be dyno tuned.. also the car bogs down and sputters when you put the gas pedal to the floor? why?

check for a burned plug wire i had the same problem

With the block learns maxed out, it means your computer is unable to control the fuel delivery properly. Until you get that under control, it is not going to run right at all.
