sounds like a lean issue, tell you what. take the vehicle to autozone and have the codes scanned and post them back here. see if somethings happenin.

Mass Air Flow (MAF) Circuit Low Input is what it means.

and that can cause your problem..

try disconnecting and removing it then cleaning the sensors off on it with some qd contact cleaner. then hook it up again and see how it goes.

check the harness for damage also.
