    PFFFE Code?

    Ive looked around for a bit about this code. Cant seem to get any straight answers. Not many people seem to know what it is, nor how to go about fixing what causes it. Im running COBB AP2 St2. I have no recent changes to the car. The last maintenance ive done besides oil changes was almost two years ago for spark plugs. My Idle has been a tad rough for a little while, but nothing huge, one person on NASIOC suggested replacing one or both of the o2 sensors, I was wondering what the replacement life on those were? The car has around 75k. Any help would be great, tnx.

    Let me google that for you

    Scan it with an actual code reader not the AP, then report back.

    Ok, so no access to an actual code reader yet. So here is what I did. I was a couple hundred miles over on the oil change schedule, so I picked up some electronics cleaner and I figured WTH, ill grab some fuel injector cleaner while I was at it, and it was on sale. I added the FI cleaner, and drove about 15 miles to where I would change my oil. I changed the oil then pulled the MAF sensor and cleaned that, then I ran seafoam through my vac system to clean things up. I reset the ECU and the CEL hasn't returned as of yet. If it comes back, ill get a true CEL reader and see whats up, then report back.
