Re: IML: surging at highway speed

[randalpark@xxxxxxx]

Don't rule out a loose timing set if the car has over 100,000 miles and 
that hasn't been serviced. You can check for this by looking for a lag 
in the movement of the distributor rotor while turning the engine over 
by hand.

Hi Robin, 
I would tend to agree with your diagnosis of a vacuum leak or a 
carburetor issue as a surge is usually caused by a lean fuel condition. 
The coil and control unit very seldom cause any problems.
