and let the memory in the ECU expire so that after you reconnected things the ECU would have to learn what the normal readings from the MAF were? Remember the part # on the MAF? And what model year?

At 90k, you are probably using aging O2 sensors and the AOS is suspect if original. And the front motor mount.

Plugs are usually good for a good while but if these other things are bad, they may be fouled. Know anything of the maintenance history of the car before you bought it?
