Please Help My Accord

I just bought a 92 accord and I realy dont want to give it back as the USED dealer wanted. I have a speed sensor code (17) commin up. Only 2nd and 4th gear are kickin in if i manualy shift this automatic (only 4th if i dont manualy). The idle goes up and down on its own in park. And i think the idle air controle valve (i see in chiltons) is missing. I'm sure i have more than one problem here, but i only get one code. Any ideas would realy be apreciated

Sounds like the dealer wants you do give it back BEFORE you figure out all the problems he didn't tell you about!!

You've got 2 choices - accept a car with probably more problems than you've found yet, or turn the car back (like he wants) and go see a dealer who isn't a crook (if you can find one :))

DON'T buy a car with a bunch of problems unless you are comfortable disgnosing and fixing things -- and the fact you posted here tells me that's not the case.
