About two weeks ago the "check engine light" on my 2005 Trailblazer
(33,000 miles) came on. I quickly took it to a local dealer to have it
checked out. I was told there was a problem with the coil & plug on
cylinder #5 which were replaced. They also lightened my wallet for the
30,000 mile service.
After getting it back we drove it around for two days and our guess what
light came on again. Back to the dealer on the 21st. Once again it was
quickly diagnosed as an engine misfire on cylinder #5.
Further checking revealed little or no compression on said cylinder #5.
They have now taken the head off for repair and it is rather iffy on
when I get it back - perhaps after Labor Day.
In the mean time I'm driving a 2006 Tahoe courtesy of GM, but this
really bites as I had planned to drive from LA to El Paso this weekend
for vacation. I'm allowed 150 miles per day on the rental from GM, so
any long trip is out of the question.
Has anyone else had any issues with the 4200 Vortec engine that required
a head job at just 33,000 miles???
Oh for the simplicity of my '69 Chevy C-10 that I can do anything I care
to on the engine without fear.
