96 s10 2.2 starts to misfire under a load when I get into the throttle
When I ease into the gas it'll run ok
but when I go slightly harder it starts
to misfire and looses power. Any
thoughts? I've changed plugs, wires,
both cool packs, fuel filter, air filter
and just can't find the problem. I
have 230,000 miles could it be
internal?
