A relatively inexpensive starting point would be to change fuel filter.

97 s-10 cutting out at constant speed...HELP

I have a 1997 Chevrolet s-10 (s10) 2wd ext. cab w/ the 4.3L V6 vortec engine and manual transmission. It has about 125K miles on it. The truck starts easily, but it CUTS OUT WHEN DRIVING AT CONSTANT SPEEDS.
It seems fine during acceleration and at idle, other than SOME CLANKING SOUNDS AT IDLE (not sure if this has anything to do with the problem or not), but as soon as I try to maintain a constant speed, it starts to hiccup every couple seconds. I am not experienced in auto repair, but research points me towards fuel pump and/or filter. Is there a way to diagnose this without fancy tools? A fuel pump is a lot more to replace than just the filter, so is there a way to differentiate which might be bad, if either? Other ideas???
Thanks so much.

Have you change locations where you fuel up lately? Maybe your getting some bad fuel. Before you spend alot of bucks on parts and repairs you might try a bottle of injector cleaner to see if it helps any.
Good luck

The problem has been persistent for a couple of months now. I don't think it is the type of gas, as I always get 87 octane, and I fill up at different spots all the time. Maybe I'll try a bottle of the injector cleaner, but I don't read very many strong "testimonials" of that type of product. Anyone out there seen it make a big difference? I am going to check out Haynes manual today and see if I can't figure something out with fuel system as well.

I have a 2003 s10 and i have found that putting higher octane gas in my truck will stop some vibrating. I would also suggest a good injecter cleaner (Lucas)

More then likely your problem is your catalytic converter. the baffling inside has come loose and causes the rattling and then causes the cat to clog... I had this same problem...what i did was just take the CAT off and break all the baffling up and make it a straight pipe basically. I dont recommend this to everyone due to emmissions checks in some states like california, but i am in texas where it isnt checked. Some people also says its gives a little better horse power boost aswell as better gas mileage. but your problem is your CAT.

Thanks for the suggestion. I have the same suspicion, as my friend and I were banging on the CAT, and we could hear it moving around. We thought about removing it, but wouldn't that set off the rear O-2 sensor or any other kind of computer check?
