MAF went out after Dyno run Well it was dyno day at my local performance shop and i've never had my car dyno'ed before. Well the night before i cleaned my K&N and might of put too much oil on it. The following day after the dyno i went to the store and on the way the car started to spit, sputter, and backfire. When i got home i hooked up the diablo tunner and found the following codes, P0101- Mass Air Flow Sensor, P0300- Random/Multi Misfire, and some O2's but i expected thoes cause i got headers. My brother has a 98 TA so i swapped out the MAF's and the code is still there, Any help or hints would be great. I tryed to reset computer but it didnt work. PS She pulled 343.5 HP, 354.1 Torque!!!

The oil coated the MAF sensor,which screwed up your fueling causing misfire's probably.
Then again if you have 02 problems you don't care about then why care about the MAF?
The 02's are more important than the MAF,so get them fixed.
Spray some electrical contact cleaner on the MAF wire's and clean them and put it back in.
MAKE SURE THE LITTLE ARROW IS POINTING TOWARD'S THE ENGINE
I'm guessing when you reinstalled the MAF it was backward's,which is why the code came back up after you reset the computer.Then again how did you reset the computer.

I think i fixed the problem, I started with checking all the plugs and putting some dielectric grease in my newly installed msd 8.5 wires. I also cleaned my MAF and K&N again to get some of the oil out of it and i restored the factory tune, it seems to be running fine now. Im going to try to put the dp tune back on and see what happens.
