Air Flow Meter HELP!!!!
I know a couple of you have mentioned that you have replaced these on your truck. What were the symptoms of this failing? I recently had a bad head gasket and had to replace a bad O2 sensor, but now my engine is running rough and it gets bad milage. The problem seems to fade in and out, but it is more rough then not. I get a check engine light with the lean message (25).
What more can I go on to figure out this problem?
If it is an AFM where could I get a good cheap one? Would a junk yard safice?

Mass Air Flow
Well on the O2 problems I would recommend taking it to a good shop for diagnosis. As for the MAF I would not get anything like that out of the yard for my truck. Don't know if your truck is 4 or 6 but the price would be the same either way through me, $425.98 to your front door.

BTW - I got the brake booster out of a junk yard for $80. Thanks for woking with me on the price of a new one, but I could go through 8 of these before I hit the price of a new one. And since mine lasted 175,000 miles and you never hear of them failing, then I figured I would be safe to give it a shot.

This is a little weird, but after I replaced my O2 sensor, I started getting codes 25 & 26. I replaced the front shocks and the check engine light hasn't come on since. Go figgure.

might be worth it to spend $50 on a used one before spending $500 on a new one.

$425 is the best price I've ever heard on an AFM.
There are electrical tests you can do to determine if the AFM is bad, check chiltons or a FSM. Oh, and I think somebody outlined the procedure here...do a search for that. FWIW, the dealer told me it's very rare for an AFM to go bad so a junkyard one might not be a bad way to go.
