Accelerator Stuck problems of the 1999 Chevrolet Astro

Caller says the accelerator sticks on vehicle. When getting in and hitting accelerator it will not move. When push ing hader it will go faster than expected. Dealer and manufacturer were notified.

Accelerator malfunctions and some times accelerator will stick on immediately after depressing it. The vehicle is unsafe.

Accelerator sticks on starting out, dealer advised that problem was due to carbon build up in throttle body and is normal. This is not a normal problem and I suspect a design problem, as no other manufacture I have heard of has this problem, dealer did advise they were having problems with Chevrolet pickups. I contacted general motors for assistance in a refund and to notify them of the defect on 8/2/2001 verbally and put in a written claim on 8/14/2001 in a letter. I was advised via telephone 11/19/2001 that no assistance would be provided and that carbon build-up causing a sticking accel. Was a normal maintaince item. It may be normal on an Astro, but it sure is not on any car that I am aware of or have driven in the last 38 years.
