Probally loose connection resulting in vacuum leak. Or the seal for the MAF sensor is not seated correctly. If the CEL is on its most likely MAF sensor related. I would wiggle all the hoses and tighten the clamps. Make sure the breather hose is connected correctly to the tubing and if everything looks good disconect the negative battery for a few minutes and reconnect and seeif they light comes back on. If it does you may have damaged the sensative MAF sensor. You can never touch the wires or get any contamination on them.
