1500 Miles trip this weekend with 94 touring wag, MAFsensor

Just went on a 1500 mile trip (750 each way)
First off, my speedo is out. the car ran like crap the first 750 there. It would miss/hesitate/bog whenever accelerating. It has alway been like this since I bought it, but I have never taken it on any highway trips-it is just my "get around town car", being it was a 300 dollar car. I have already previously switched trannys. When I got home to my parents, the car was dry underneath for about an hour, then all of a sudden there is a huge puddle of ATF. After arriving at the destination, my dad (40 years as a mechanic) looked everything over. He found the ATF leak-it was a leak around the tranny dipstick where it mounts to the tranny. New O-ring and now no leaks. For the bogging/miss/hesitation, we checked the check enging code (I new it was going to give a code 33 speed sensor due to the speedo out)
It gave 3 codes-nock sensor and mass air flow sensorMAFS, plus the speed sensor)
So, we re-repaired the splice on my nock sensor wire. And then my dad looked at the MAFS and it looked clean, but when he took out a alcohol wipe pad, it definitely had dirt. After cleaning it, we started up the engine, and WOW WOW WOW, it ran like it was new. It would rev to read-line no problem. I was smiling, so decided to give it a test drive-and i could spin all four wheels on take off. So, now my car is awesome again. I got 25 miles per gallon the first leg of the trip, and it would hardly run above 70-mph without cutting out. On the return leg, I got about 29mpg (also increased tire pressure)and it ran without missing a beat. I could keep up with ANYTHING on the highway. Without a speedo, i am lucky no tickets are in my pocket. I am running a K&N and attribute part of the dirt on the MAFS to the oil coming off it when the filter was new. But the car had the problem even before I put in the K&N. Anybody wanna race now?
