How to get to fuel injectors

Unread post by Udey » Sat Mar 02, 2013 1:44 pm

I'm getting a misfire on cylinder 3 I've changed the spark plugs , changed the coil and the cam sensor and it's still misfiring. Now I'm trying to check the injector but can't figure out how to get to them. I have a 2005 chevy trailblazer lt inline 6.

The injector rail is right along side the intake manifold. I can tell you this, though, it probably is not a fuel injector problem. The cylinder heads have been known to have issues with the valves which will cause a misfire condition. This will normally require cylinder head replacement or repair and is not an easy job, or cheap either. Before you go assuming it's a bad fuel injector, you should really have it checked out by someone that is familiar with those engines before spending any more money on it.
