That would rule out a vacuum leak in the EVAP system. Go over all the vacuum lines like the power brake booster, the PCV, etc. Maybe try swapping the MAF out with someone else to see if that is going bad. If the MAF is faulty, the stock programming may cause it to run rich to protect the engine from leaning out.
