Just a thought; I had this problem in my Vette and the only telltale that I happened to see by accident,was a wild tach needle while the hesitation was occuring. It turned out to be a tach filter (filters out stray electronic noise that could effect the tach signal.)
It took forever for them to figure it out because no one had ever had one go bad. So watch your tach needle to see ifit fluctuates wildly.

This is to both mike2250 and gigglein. I have stumbled across a partial fix. I had just had a letter from GM stating that "all Colorado Canyons with 5 speed transmissions and 5 cylinder engines do this and it is a trait of the vehicle and they will do nothing about it".
In frustration something made me turn on the ignition but not start the truck. I then pressed the accelerator "to the floor" three times rapidly and something, I assume the PCM let out, via the radio, three or four "beeps". The next time I drove the truck it seemed better. The hesitation is still there but not nearly as pronounced. It also seems to have more "guts".
What I did I have no idea but a mechanic relative says he thinks I "reset" the relationship between the throttle position sensor and the computer. The "backfire" is still there when starting hot but as TECH said maybe it's just a little unburned fuel from the shut down. Try it and let me know. Maybe I'll prove to GM yet that they don't have a clue what they are building anymore.
As to mike's suggestion about the tach, no, mine is rock steady. 1RG

I'm tired & frustrated. Any suggestions on what tire I should consider for replacement of the General Ameri-Junks on my 2004Colorado Crew Cab 4x4 Z71 package? Tire size is P265-75 R15. Thanx

I have a 2005 5 speed regular cab. I too hated my 205/75/15 General junks. Truck "wobbled" every time you crossed a rail track or anyting like that. TRowing my camper was a nightmare even with 45 psi in them. I traded them for four Yokohama 215/70/15's and what a difference in handling. I am sure a 65 profile would be even better but the change in the circumference would start to effect the speedo too much for my liking. I am running standard 6" rims. RG

I put Goodyear Wrangler Silent Armor on my 2006 3.5 4x4 reg cab and think these are the best tires I've ever had on any truck.

Any advice on buying a Colorado Crew Cab. It is a '05 4WD LS Z71. Mileage is 19600. Looks to be in excelent condition. I think I can get the truck for $19000 tax & title included.
Power Door Locks
Single Compact Disc
Dual Front Air Bags
Any input would be great.

Replace your Generals with a 31X10.50r 15. BFG All-Terrain is a good choice. The Goodyear one mentioned as well is also a good choice. You can do some research at tirerack.com by typing in the size. The 265/75 r15 is basically the same size as a 31x10.50 r15 so you wouldn't have to worry about speedo changes and such. The 31 is a flotation tire size and not a "P" series size. Meaning the 31 is geared more for offroad, but there are several tires out there that are also more "road" worthy. In the 265/75 15 there is not as much selection.
