hi I have scand my car and it threw up this code 16486 I know it is for the maf would this mean the maf is dodgy. I have just cleaned the censer and housing it did not throw the code be for I used electric contact cleaner on the censor and fairy liquid on the housing and it was dry when I put it back and that's when it started running rough. it was intermintnetly running rough be for I cleaned the maf do you think I should replace the maf and see if it cures the problem
