All of you MAF guru'* out there....(fixed)
Hello,
Engine stumbles at low load/rpm. Idles fine, high rpm/load runs great. been through ignition parts- all ok, plugs and wires replaced. Car had cat replaced because of noise a month ago. I unplug MAF low rpm stumble goes away.... Replaced MAF with NAPA part, car stumbles as it did before. I unplug MAF car runs great. What am I missing here?? Crazy Bonne

UPDATE:
Checked all connections... Car runs, idles great, then in a flash sputters under load. I noticed the egr clicking. Unplug the egr, no flow of gasses into intake, car runs great.. Plug in back in, car stumbles under 1500rpm load. Does this sound like a vacuum leak and ecm is energizing egr, which make lack of vaccum in intake worse (resulting in rough operation) Am I thinking right? All of this rough operation occurs around 1500 to 1800 light load. No codes btw

Thanks for the reply btw. Checked out the pipe- no cracks.. Right now, i am riding aound with the EGR unplugged and the car runs great-of course I am most likely causing myself big issues down the road...
