Its got me...Chevy Blazer will hardly go.
99" Chevy Blazer starts fine cold or hot. Idles perfect..excellerates in park just at first..Put it in drive while holding the break,Idles normal. Release the break and excellerate and she wont die,but she'll hardly go either...Checked fuel system from pump to engine back to pump.Nothing wrong there.Checked maf & vacuum, all checks out...tranny,transfer case,no noise,no smell,oil still red.Had the c.c. changed by a pro shop.still have good combustion...5 stars to the one that can figure out this one,,,Much Thanks
