I got a 91 s10 blazer not long ago. It have been sitting for a while and havent been started in a year or so.
(its 4.3l with TBI)
It starts just fine even with low voltage in battery it starts easy. But it just want idle and when I am giving gas it just doesnt go right.

So I changed the gasoline on it, filter, sparkplugs, sparkplugs wires, rotor and cap. (The pump is working, air filter looks good)

But still it will not run good, so i am starting to run out of ideas...

Any good advise for me????
