2004 Chevrolet Trailblazer
Two months ago I bought a 2004 Chevrolet
Trailblazer and have had no issues until now.. 2
days ago the Service Engine Light started to flash
when I would accelerate to go up a hill. The oil was
recently changes as well as we used gas treatment
to help clean it. It only flashes when we accelerate
up a hill besides that it runs fine.
