Today when i was on the interstate i began to notice the truck started lurching when i was going up hills in 4th/5th gear between 45-75 mph.

    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...
