| While replacing the fuel injectors under a special injector warranty, the dealership broke a glowplug off and called to say i need to replace the cylinder head at my cost. call gmc customer support who say due to the age and mileage 2001, 124500. that the corrosion of the glowplug and the fact it seized in the cylinder head is not there problem, even though they are the one who designed the engine. they said that it's at my cost for a new cylinder head which was quoted to me over the phone at a price of $1,800.00. *tr | |||

| The accelerator sticks and is extremely difficult to depress. the carburetor design allows carbon to build up in the throttle body throat. i often have to hit the accelerator with my foot to dislodge the butterfly. this happens worse after the vehicle has been setting for an hour or so. it will also happen after departure while setting in traffic or at stop lights. i use mid grade fuel and the truck is well maintained. the dealership wants to charge up to $100 to clean the carbon out only to have it return in a matter of months. i have talked to others that have experienced the same condition/problem. in my opinion this condition is a true safety issue. *jb | |||
