Pat,

I own an 88 convertible that used to be Jerry Hey's. Same miles on the 
odometer as yours. Just drove it from Chicago to Colorado for my son to use 
while he's at the Air Force Academy. Ran great. Got 23 mpg at 75 mph with 
the A/C on full.

Some ideas you've probably already thought of:
Air filter okay?
Do the injectors need to be cleaned? A pretty cheap fix, though you've got 
to peel the whole intake manifold off to get to them.
Factory computer? Then you've got less of a chance of an ignition issue. If 
it's got an after-market computer, then you've got the possibility of bad 
timing.

If you've got air, fuel and spark at the right time, that's the short list.

Vacuum leaks tend to show up with bad idles or wierd things when the car is 
going from fast idle to regular speed.

Maybe a plugged cat? Mine just got an "improved" exhaust and that pepped 
things up quite a bit.

Given that you've owned three 88's before, you must know what's "normal" and 
what's not.
