maf issues p0101 | Buick Forums Feb 26, 2014I have a 2002 buick rendevues with 130 miles. It started Reving up really high (past 4000 rpms) and stalling sometimes. otherwise need a very careful/closer inspection of wiring, hoses, intake gasket, EGR/gasket, exhaust pre-o2 sensor. might be somewhat interesting to know the other codes i can guess p102, p0171 like that .
