You can clean the maf with some electric parts cleaner. Try doing a search you should find tons of info on this problem. Also pleas post your question in one section only. Sometimes it takes time but people will respond.

Check the MAF plug-in socket very carefully. Ford has had problems with them in the past. Look for corroded or loose terminals.
