I drove my 2010 4 cyl Camry from Indiana to fla.100 miles out it started jerking intermittently and slowing down in power I got off highway code said po 171 so I replaced MA's airflow got back on highway and drove 5 to 10 miles started doing same thing. took it to shop they tested everything .couldn't fine the problem.now when I drive the car about 30 miles at speeds of 55 or so it starts doing same thing.what's wrong
-
There are some test that needs to be done to determine exactly what the problem is, but the most common problem is the "Air/Fuel Ratio Sensor". Before you replace any more parts, check the hose (duct) that goes from the air filter box to the intake. Sometimes the hose gets cracked and cause the same symptoms.
