90 aod sc with check engine light. koeo gives me a 66 in the computer memory. the book i have says high voltage at MAF sensor. do i need to replace this? if i do need a new sensor can i get a high performance one even though right now my car is totally stock? (minus air silencer) also, when i put my car in gear she hesitates moving til i give her gas even with my foot off the brake. is this early signs of transmission problems? just bought the car not to long ago and i have yet to drive it. the car has 76000 miles i am the third owner, but the second owner drove it for about 500 miles then the abs went out, has been sitting for a year.
