Throttle stuck wide open I had to depress the clutch and turn the engine off. This has H appened five other times at various speeds and under different weather conditions. GM know of this problem it has caused accidents and they refer you to the dealer. Their dealers do not have a fix for this problem and they know this information. This problem is showing up in all F-body GM cars with their 5.7 liter V8S. I have not reported this problem to my dealer because I know they can not fix it. This is a problem that is not consistant. It does not happen if you preform a given task. Once I started my car after it was sitting all day the tach raced from 900 RPM to 4,000 RPM. I shut the engine down and restarted three times before the problem was corrected. Once, I was exiting I-96 freeway at orchard lake road exit I had been driving at 70 mph with the cruise control on. When I applied the brakes to to slow for the exit the engine shot up to 5,000 RPM from 2,100 and the car went from 70mph to 90mph before I put the clutch in and applied the breaks. Another time I was driving on North bound telegrath road between 14 & 15 mile roads at 50 mph it was summer time and I had the air conditioning on. I applied the breaks to slow down and the engine again went from 1,800 RPM to over 4,000 RPM. I again put in the clutch, and remembered that I had read a post about this problem on the internet, so I turned off the air conditioning and the engine went back to normal. This is a very serious problem, someone is going to be hurt or killed. If you go to the slp engineering web site (www.slpeng.com) you will find that there have already been accidents caused by this problem. I believe that there is either a deffect in the PCM or in the wiring harnes that controls the fuel injection system. Taking the car to a dealer will not be of any help. This is an engineering problem. Please help us! thank you, [xxx]. information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
