I have been having some detonation and hessiation from my car in the last few days.. I have done alot of playing with the overall fuel ratio via the ecu but I dont know how to check to see if its all calabrated correctly under the hood? I checked the intake blocks and they seem ok.. so I am not sure what might be the deal.. I might have some fouled plugs or something like that but any help on adjusting air to fuel ratio would be awsome! Ahh and maybe some info on how to verify the .o2 is working?

the base Idle setting is stamp on top of the air flow meter. adjust the set screw and measure the depth from the top surfase of the air flow meter to the top of the adjustment srew.
you would need a dial caliper to do this.or a depth gauge.this is ofcourse assuming you don't
have any vaccume leak.
