Default uneven acceleration

long time reader....thanks to you all for the many ideas....now I need some advice....2003 pt gt...24K, in great shape...BTG intake, BTG springs,BTG strut tower brace...lots of added chrome...etc..in the last 2 weeks with both the cruise contol on and off, and at various speeds the engine will accelerate on its own for a second or two at a time..then resume normal operation......no missing, but a very brief but noticeable acceleration, like the motor is looking for another gear...then resumes...most noticeable at 2500...70 mph with the cruise on....should I reset the computer...if so....how do I do that?.....any suggestions would be most welcome....thanks again...and for all the past info...Jim

Mo-Cash,

Welcome to the forum. You hit the nail on the head with the easiest solution...reset the computer. If you've installed or played with the modifications you described, you know how to access your battery. Find the negative cable and unhook it from the post. Leave it off for a few moments and then re-attach it. The car might stumble a bit when starting and running for a few minutes while it re-learns the settings. Take it for a ride and go thru all gears and go as fast as they legally permit in your area. Then try the cruise control again. If it still does the surging, You have a bad cruise or you might have a vacuum leak somewhere. Good luck.
