gb3803 Posted September 15, 2007 Share Posted September 15, 2007 Hi All! I am a newbie to this Forum and need some help. I own a 2002 SC430 with 78,000 miles, love the car and ride but here is the problem (bought it used 2 years ago). When driving the car 20 to 80 mph range the car decelerates automatically. It use to do this every so often but it seems to do this all the time. To compensate when driving, I need to push the gas pedal down 50% more to keep it at the same speed. However, when I put it on cruise it doesn’t happen. Any suggestions and/or comments would be most helpful. Thanks, Glenn Quote Link to comment Share on other sites More sharing options...
johnsonhuang Posted September 22, 2007 Share Posted September 22, 2007 the car is supose to cruise on a flat surface at 40-50 mph no problem. if your starting to slow down alot when u let off the gas pedal, u might want to check your alignment or camber.
