You could try to change the O2 sensor(s).. They are alot cheaper than the MAF, and it seems to me, on my little truck, that is usually the culprit. It's one of the points that tells the comupter how "lean" or "rich" the engine is running. If some crude got knocked loose than it could've "latched" onto the sensor. Some of the injector cleaners say "safe for O2 sensors" or at least all the ones I've seen do.


You'd be suprised how many times those (O2) are the answer to why it's running like crap..
