Hi, I’m Cary and I’ll be helping you today.Please understand that I can't smell, hear, or touch the vehicle, so patience is appreciated. Before leaving the site make sure and leave me a rating. You can still reply to me as many times as needed, even after the rating..
Does the vehicle loss power or does it shut off? Or both?
Was the MAF sensor replaced because of a check engine light and to try and correct this problem?
It is possible that the cat conv is clogged. The best way to test that is to remove the exhaust pipe from the manifold so the exhaust gases can escape. Drive it and see if that helps. Does it lose power at higher seeds and rpm?
Sounds like clogged exhaust for sure. Sometimes a clogged exhaust or other drivability problems will cause a MAF sensor code. Are you going to fix it yourself?
Remember if you rate me we can still continue the discussion. Five star please.
There is no cleaning it. You would have to replace the Catalyst Convertor. Muffler shop.
