When did OBSs (in the US) switch from MAF to MAP sensors?
(I'm shopping for '99-'01 ans ran across info that maybe '99 had maf)

Wow, tough question Carl. IIRC the OBS was odd in that 1999 was split between MAF and MAP. I think later in '99 it was changed to MAP. I also think some engines had MAF and a MAP sensor in '99. Personally I like the later MAP's but the MAF's I hear are better when it comes to tuning.
