I4/I5 Engine & Drivetrain
2004 Colorado Ext 4x4 Z71 5cyl.
I'm the original owner.
Drove it off the dealer's lot August 26, 2004.
Now, at 7 years 4 months and 117k miles, I get the "rough idle" misfire with the code.
The recall extended the initial warranty to 7 years and 100,000 miles.
GM is about to lose another...
