While driving the vech. once it goes under 10mph it will stall out. i then have to put it in n and restart. this has been going on for a while. ever since it about 40-45,000 miles...i have not been able to afford to pay to have it fixed. i was told by a chevy dealer service manager that it has a faulty coil system and chevy does know about it but when they choose to issue a recall notice is there choice. *tr | |||

Vehicles check engine light came on then went off after a couple of days. vehicle idle dropped to 500 rpms. the truck started to act sluggish and acted as if it would shut off at idle. during acceleration the vehicle was again sluggish. took the truck to a local shop and had the codes run. it came back as an engine low rpm code. i don't recall the actual code number. had them do a motor vacuum to clean the fuel system and reset code. the check engine light has gone away and has not come back on. vehicle does from time to time act as it is going to bog down. i thought that i should submit this complaint because it seems there are several others with the same problem.*ak | |||

My 2004 chevrolet colorado has had repeated a recurring problem where it will not respond to the throttle at all while driving. in all cases this has happened when the engine is warming up from a complete cold start in the morning. while driving at 45-50 miles per hour the engine will drop to idle speed and there is no response to throttle input. the dealer has had the vehicle in for service on this issue 5 times now and can nothing wrong. there are no codes set in the computer and the check engine light never comes on. the problem will clear itself after 20 to 30 seconds and may not occur again for weeks. *tr | |||

The check engine light comes on accompanied by an engine misfire due to weak exhaust valve springs which must be replaced. recently gmc issued a bulletin to their service departments advising mechanics on the issue, and recognizing the problem with the valve springs and how to fix it, but will not acknowledge a manufacturer's defect. according to the bulletin this problem occurs in all chevrolet colorados 2004-2006, gmc canyons 2004-2006, and the hummer h3. the estimated cost of repair is about $2000, quoted by the dealer mechanic. not only does the check engine light come on and stay on, it also causes the vehicle to stall while in operation. the truck shut down in the middle of the intersection while driving. additionally you will have difficulty when you start your car, it will misfire and you may have to restart again. this will begin to happen regularly until you diagnose the problem. i went to different dealers to diagnose the problems because different mechanics could not find the problem with the check engine light. the last step was a dealer mechanic that had just received the above mentioned bulletin. they did not fix the problem with the valve springs, instead they reset the computer to stop the check engine light from occurring. the misfiring and stalling continued to happen.*ak | |||
