My dads mechanic is coming today to change my back brakes. What do i ask him to check/clean? What is a good product for the MAF? Can i find it in the car section at wal mart? or do i have to go to discount auto parts? Im also going to get the autolite double platinum spark plugs for him to install. And do you think i should change the o2 sensor also?
BTW, i filled my tank on wednesday with $25 exact and i had 189.4 miles on the tank when i refilled it. Its getting worse. The gas kept going up and down i had to drop my friend n her friends off to go get gas because i didnt know how much i had

Thank you every1 for your help,
Robert
