Temple, I fixed this on my 92 back when I had it. There are other trheads since then where the same happened. Pretty easy to do along the lines of what's been discussed above. If it happened again, I would fix in a second if I couldn't quickly find a replacement for cheap.

I was just at the yard yesterday getting the MAF for Marius. The 91 I was in is clean for this area. Not sure on the drop-in unit though. It's at a Pull-A-Part. If it's good, it would be ~$25 with the pump. Not sure when I'll be back though. It's cold here and everything there is buried in snow. If you get jammed up with this, let me know and I'll see...
