Code 41 & 91. Any Ideas?

Hello,

I have a 91 GT Automatic. The check engine light seems to come on after warmup during deceleration.

I have codes 41 & 91 in continuous memory and during KOER.

I have replaced both HEGO's, cannot find a vaccuum leak, checked EGR function and am now out of ideas.

Any help is greatly appreciated.

Thanks

assuming no idle problems, esp on A/C switching on and off.... then check the air injection system.

i'd think it would shut down injection on deceleration.
