Re: S-10 Blazer hesitation when accelerating only.

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?

Re: S-10 Blazer hesitation when accelerating only.

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!!!!!!
