| Vehicle Speed Control problems |
While entering freeway have to depress accelerator peddle 1/4 to 3/4 of the way down before acceleration begins. From stop and merging into traffic have to depress accelerator 1/4 to 3/4 of the way down before acceleration. Entering freeway or fast starts, accelerates then dies off then goes again. On hill starts it sometimes rolls back as if it is in neutral. These are intermittent problems at varying degrees of severity .
With the speed control engaged and while pressing the deceleration switch on the turn signal arm to slow the vehicle down, the speed unexpectedly increases. Each press of the deceleration switch normally causes the speed to be reduced by 1 mile per hour. The first few presses cause the vehicle to decelerate as it should, but occasionally on the third or fourth press the speed jumps back up by 2 or 3 mile per hour. Sometimes it corrects itself and sometimes it keeps repeating the pattern.
