My s-10 I've been having a bad recent problem out of. It idles rough for a few seconds then idles right, if you put it under a sudden load it skips. If you ease into it it has like a bad/dead spot where it goes down to 500rpm or so and picks back up. Which sensors would cause it to act like this? I can think of the TPS, CPS, KPS and MAP sensor. Or does anyone know the specs for a fuel volume test?
