try cleaning the MAF sensor. i had the code p0171 replaced both o2 sensors,spark plugs, pcv, air filter and wires. Washed the MAF down with som carb cleaner and then electro wash and CEL has stayed off.



Actually, this was the first thing the shop did, way back in September when I took the car to the shop for the first time. Didn't fix the problem unfortunately.

When I visited the shop last week, he was suggesting that a new MAF was the next step. I have a feeling this would cost me a ton of money plus I'm not sure if it would solve the problem. For example, I ended up buying new o2 sensors and it wasn't even the problem!

If anyone has any costs or other info on the MAF I would greatly appreciate it. Could it be faulty?
