Help, self inflicted problem!

[PeterBergin at aol.com]

Looks like I may have did it this time, Changed oil and cleaned and oiled my
K&N air filter (first time for the cleaning).  Started up, noticed some
missing, went for a test drive, had a lot of missing during acceleration.

I assumed some excess oil from the filter got on the MAF sensor, cleaned
sensor with some brake cleaner, restarted and ran better.  I still have some
missing or hesitation when accelerating.

Any ideas.  I hope that this doesn't turn into a classic case of self
inflicted stupidity!
