Need help with s-10 blazer (91) I have done nearly everything to it as far as tuneing it up and replacing the computor still I have this hesitation when accelerating . Has anyone had this problem If so please help. :banghead:

its something with carb i think i have same problem if i get it fixed ill let you kno or if you get yours fixed let me kno. is it a 2.8L

I own a '93 S-10 2WD. W in VIN code. I am having the same problems. I have replaced EVERYTHING. I don't have an answer for you. Welcome to my hell.

oh wait 91 has tbi mine carb. well mabe its the timing

Hey! I had the timming all checked out and still the same thing, yeah it's a 4.3 . I replaced so much crap I dont know what to do next.

check 1.coil or coil pack 2. clogged injectors 3.fuel pump pressure 4.fuel filter 5.fuel lines 6.timing these are what normally cause hesitation when acceleration

I had the truck at a local garage and they did check the fuel pressure and return line wich checked out ok. The timming also is right on but I should check the injectors?

After changing the electronic spark controll module mounted on the fire wall and the pick up coil it finally fixed the problem. Now its victory beer time!!!!!!

have one for me
