Question about 2004 GMC Sierra Denali
Last spring I had the check engine light come on after the engine started missing.
I found that #4 cylinder was misfiring from reading the code at my local napa.
I cleared the code and drove home (35 mi.) without any parts.
I pulled off the plastic over the engine and found that rain water was shorting out #4 spark plug.
After vacuming out that area around the spark plug, put everything back together, The trailblazer ran fine.
No more missing.
No more codes.
There is a TSB (technical service bulletin) on this issue , with directions to install foam weatherstrip to the AIP.(air intake panel) . TSB #06-06-04-048b
