Ken,
I can help out with the ABS sensor...I've got a couple extras since I'm changing spindles...Then you can help me out with my SC rebuild and porting...
And the MAF can go bad. If that is the case, then go with an aftermarket one. The injectors may sound "hollow" because the MAF is bad. Fix the MAF first, then you can tell if the injectors are bad. I'd go with a C&L unit since you can get replacement sampling tubes for different size injectors. Then you can still save your $$ for the paint. I'm hoping to get to my suspension in the very near future, so the sensors can be used, as long as we don't break them while removing them.
You might try cleaning the MAF with throttle body cleaner to see if that helps. Do you have a K&N on there? If so, you can get too much oil sometimes and that can get onto the MAF, causing it to act as if it were bad. Just a thought.
Edit: and to go along with bigslide, try running a can of BG 44K through the fuel system. That will clean all fuel related components in addition to a little more. I can pick up a can for you if you can't locate it around there...although you've got better availibility on most things than we do here in Lincoln.
