Re: 91 s-10 truble
The 2 things that I would do is first check for any vacuum leaks. If the motor rev's up while spraying WD40 onto a vacuum conection you found a leak.
And if that doesn't work do a complete tune up. Including change the fuel filter. If you haven't changed your fuel filter in a while change it anyways. The best way to burn out your very expensive fuel pump is by letting the fuel filter get plugged

Re: 91 s-10 truble
Oh, Welcome to the forum! I hope that you check in from time to time.
It's nice to see someone that does a tune up when it might help. It still sounds like a vacuum leak to me, so that is where I would start. I didn't really think that a tune up would help, which is why I didn't write it down first. But it does solve most problems that people have
