Mercedes-Benz 1998 E320 - 160,000 Miles Strong
So basically I got the p0173 & p0170 codes I took out my original MAS cleaned it out with CRC MAS Cleaner (grey aerosol bottle) let it dry and whatever. 10 miles later CEL. I buy a used MAS for $50 10 miles later Check Engine Light cleaned with CRC same thing. So basically cleaning a broken MAF is useless is what I'm saying I believe the only time to use this product is on an already working MAS. Is there anyway to test these things with a multimeter? Could these specific error codes relate to something else?
