#64 of 234 1994 gmc sonoma hestitates on excelleration rough idle
Jan 22, 2007 (8:13 pm)
My 1994 seems to hestitate on light exceleration and sometimes backfires or pops throu the throttle body.IT seems to idle rough sometimes also. My light came on so i read the code and it said my idle valve was bad so i replaced that it ran smother but still have the same problem. So today i changed the fuel filter but i still have the same problem. Anyone have any ideas?
Thanks in Advance

my 1995 gmc sonoma has been running great until three weeks ago the weather got warm. my truck started to pop and backfire when accelerating. i was leaning towards fuel problems or maybe distributor when it got cold the problem went away for about a week and a half. the problem has returned again and its cold outside. continuous popping which sounds like an old car witha a carb the the engine is back firing through the carb. i have been told its something electrical. anyone out there have this problem or a possible solution.
#66 of 234 2001 gmc sonoma stalls and idle is off

Truck stalls when at stop signs, lights, and when going around corners slowly. It will always start right up again. This tends to happen more often when the tank is below half. When the truck is in park it doesn't have a constant idle, rpm's lower almost to zero before going back to normal. When truck is about to stall tha battery guage halls off to the left slowly sort of like it's giving me a warning. If I could get some advice it would be greatly appreciated. Thanks

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

#69 of 234 97 s-10 cutting out at constant speed...HELP
Jan 19, 2007 (5:56 pm)
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.

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.
