Question the next thrilling installment...

After much toiling I have found that i did not blow yet another MAF. however, the OBD code I pulled when I got the part said a low voltage from the throttle position sensor. I d/c'ed the battery and reset everything and the car will run fine. before that it did the dreaded "MAF hesitation" at 3200-4000 RPM. Has anyone else experienced a problem with this sensor? I adjusted the throttle cable to take some slack out of the cable, and Buster helped remove the silencer.
Any ideas?

in havent heard it refered to 'maf' hesitation. subaru technical service bulletin #11 58 99 recommends replacement of ecm. it also has been refered to as a knock sensor sensitivity issue. now you are telling me it is a maf issue? argh! - i have had this problem on and off for a year now.

The hesitation is the knock sensor, I fixed mine by putting a small gasket under it. 1200kms and it is not back.
