P0421 - 2002 Protege 5
I was having some stumbling in the Protege and got this plus another code I forget. They were associated with a dirty MAF. I cleaned the MAF (just a can of spray cleaner) and it runs more or less smoothly, but this code came back. Now goddamnit, my cats were replaced not too long ago!!
Paul, what gives. |
You made sure you used rubbing alcohol or MAF cleaner right? Carb/brake clean isnt the same and leaves a film that fucks with the sensor.
The other code would probably help in the diagnosis. |
MAF cleaner yes. I'm pretty sure the other code was P0171.
|
p0171 is a lean code. Most common causes are vacuum leaks, intake air boot leaks and dirty or messed up air flow sensors.
|
I'm gonna be a bit pissed if the NEW cats were damaged by a lean condition from a dirty MAF. . .
