98 2.5 problems
 

So tonight I was sitting at a light and when I went to take off the truck fell flat on its face. So I limped it to all places a Ford dealer I was by until I towed it home.

It will idle just fine but when you give it any about off gas it will rev a little and just fall and continue to do that no matter the pedal position.

So first I thought timing belt(122k miles)but it still idles perfectly. Can the computer compensate if the belt slips a tooth?

Second I thought fuel pump or filter going out or clogged but when you try and rev it up it you can smell fuel.

When I towed it home I stopped by autozone and had them pull codes to see if anything showed up but there was nothing. I did not get a CEL.

I figure I will pull the timing cover tomorrow and check that but does anyone have any other ideas for me? It will still start and idle fine so I'm lost.

Never mind it was the MAF. I wonder why it didn't throw any codes?
