fuel injectors
noticed my H2 idles little rough, had tune up done at 100k and now at 134k. my mech thinks it id injectors or manifold. question is has anyone replaced there injectors on there H2 and how hard is it? I seen a few videos and it seems easy but I am no under the hood guy. I just want to know how to do it and how to remove the fuel pressure.

actually yes diesel,. just actually talked to him last nite. I have a old Hummer certified mech who only works on my h2....he suspected head gasket seal and prob plugs. He said they were known for the seal going. I have 134k on mine so he actually said he thought that was it. He tuned and replaced plugs at 100k but said he will check cause he thinks one maybe bad. but thanks for the feedback guys.

has anyone figured out the random misfires
Had this going on for awhile, replaced the battery and it went away for a few hundred miles. Cleaned the throttle body and replaced the MAFS. I still get the code. I run the engine/fuel injector cleaner and it goes a way for a few hundred miles and pops back up...any thoughts? Is it the plugs or cables?
