Question

2005 Chevrolet Trailblazer LS with codes p0300 and p0350. Are they a manufacture recall on chevy trailblazer with this problem?

Answer 1

Hi there,

P0300 is a random misfire code. This can be the result of several different issues that have to be tested. There isn't any recall, but there is a service bulletin for some models. Find more here:

P0350 doesn't appear to be a valid code, although without knowing the engine size I can't be sure.
