[DML] Re: Strange acceleration problem

["Harold McElraft" <hmcelraft@xxxxxxx>]

That is usually caused by the vacuum delay valve at the fuel pressure 
regulator coming loose or possibly a problem with the fuel pressure 
regulator or vacuum hoses attached thereto. The fuel is too lean and 
causes the pop-back in the intake. The hesitation goes away when the 
engine warms up but it needs a fuel spike when cold - that's what the 
delay valve does. Be sure the dist. side of the delay valve is facing 
the firewall. The delay is suppose to be 10 seconds. The color side is 
usually the dist side and the color indicates the delay. I think the 
proper delay color is white or gray - you can test it easily enough.
