Hmm....

In my book, the distributor cap, rotor, and the fuel filter would be the
'first' things to replace, not the last.....

You could have a 16 year old distributor cap in there and I will bet the
fuel filter 'is' 16 years old....

My 88 bogged down like that once. When I went to replace the fuel
filter, it literally crumbled to pieces.

The MAP sensor is on the firewall center on those I believe with one
vacuum line running to it.
