2000 Blazer - Idle only
try to make long story short - Blazer overheated, cracked head! Got a used head, machine shop magnafluxed, valve job, seals, surfaced. Replaced all hoses, plugs, wires, cap&rotor. Ran good for 2 days, maybe 20 miles total. Drove today, little longer distance, died at idle. barely made it home, now the engine dies with any accelerator! Off idle, dies, With every 4-5 attempt, I can rev it over 2K rpms, it will keep running, but dies, as soon as you reduce rpm. I checked EGR valve-working fine, not that dirty, checked fuel pressure, looked fine (replaced pump and regulator about 4 months ago). Appreciate any ideas!!
