Based on the info provided, it definitely sounds like the MAF is bad or is not connected very well. Check the connections to the MAF first. If that does not seem to work, try a friend's SR MAF or a KA SOHC MAF to see if that remedies the problem.

Hey thanks for the tip. Also the connector is bad.. it wont snap in at all its all lose and it slids right out easily. . I if I was to replace it could I buy from a parts store?? The connector thats attached to the harness part.
