The defect
INSUFFICIENT CLEARANCE BETWEEN THE AIR/FUEL MIXING REGULATOR AND THE THROTTLE HOUSING COULD ALLOW THE DECEL SOLENOID LINK ARM ON THE THROTTLE TO CONTACT THE MIXING REGULATOR UNDER CERTAIN EXTREME DRIVING CONDITIONS. THIS WOULD CAUSE THE ENGINE TO ROCK TO THE LEFT ON ITS MOUNTING. FULLY DEPRESSING THE ACCELERATOR WHILE MAKING A SHARP RIGHT TURN AT MODERATE TO HIGH SPEEDS COULD CAUSE SUCH A CONTACT TO OCCUR. FURTHERMORE, MOVEMENT OF THE THROTTLE PLATE MAY MOMENTARILY BE RESTRICTED DURING THE TIME OF CONTACT BETWEEN THE LINK ARM AND MIXING REGULATOR.
The remedy
THE DEALER WILL REPLACE THE LINK ARM WITH A MODIFIED ONE TO ENSURE SUFFICIENT CLEARANCE TO THE MIXING REGULATOR UNDER ALL DRIVING CONDITIONS. THE POSITION OF THE DECEL SOLENOID MAY ALSO BE READJUSTED IF FOUND NECESSARY.
