Tom,
There was a TSB for the 2.8's with the MAF system, that called for a
replacement eprom... The new eprom disabled the maf, and it could be
removed... I believe it was done on the fiero's before any others were
affected... I have the eprom part numbers at home... I'll post them tomorrow.
Later,
Dave
