    I suspect you have a vacuum leak somewhere in the intake plenum or the intake manifold. First check all rubber hoses going into the intake manifold for cracks or leaks. Next, spray some carb/throttle spray cleaner around the edges of the intake manifold and see if you get a momentary surge. Next, remove the MAF sensor in the intake plenum and clean the sensor wires with CRC sensor spray as per the directions on the can. Next, remove and clean with the throttle spray your EGR valve. Finally, test your throttle position sensor for proper operation with a voltmeter. There is no additional cost to any of these steps other than 10 bucks for the cleaner and it may resolve the problem. Good luck!
