i think he means MAF. i could be wrong but sounds like a MAF problem. try cleaning it and checking all the connections. can you see where those wires came from?

Change the oil--then check the temp sensor,o2 sensor,tps and make sure that your getting the proper voltages from the maf.

Can yo pull the codes?

here is the thread on how to pull the ecu codes. read it then post what codes the ecu gave you. it will help you pinpoint the possible problem

MAF is an AFMAir Flow MeterMass Air Flow meter

same **** its like saying thats a car instead of a 240, just a more general term.
