truck's dog-ing

[CrimKsie]

99 4.3 S10


It feels like when I step on the gas anywhere I go I have to push a lot harder, it almost feels like I'm towing something or the truck is holding back, what's going on? Any ideas anyone?

thats nothing new for my 4cyl....lol but seriously it could be clogged injectors, my friend had a problem like this, run some 93 octane through it and put some injector celaner in it the next few times u fill it

umm i had these problems before but it could be alot of things , so im gonna give ya a list of stuff to try out

1st clean thottle body at 60 k mine look like nasty
2nd check all vacums disconect an reconnect
3rd check spark plugs if havent changed em in 40 k
4th get it coded / even if the ses is not on , take it to autozone or adavnce auto parts an they run it for free
5th check air filter

lemme know if it works out

I had the same problem with mine not too long ago, it ended up being the fuel injectors, I just put cleaner in it the next 3 or 4 time i filled up, it fixed it,
must be a pretty common problem with 4 cyl

Those gumout additives you add to your gas tank also help. You can find them everywhere. They should help too.
