Question is, going down the road holding speed at any given speed it tends to start surging really bad, I give it more gas pedal it straightens out. i just bought the car and it had been sitting up quite awhile. are there any suggestions or answers that i can check into ? Thank you
 
I'd change the gas filter then fill up the tank and add some gas treatment and then after a few tanks of gas change the gas filter on it again.Clean the spark-plug wire connections and clean and re-gap the spark-plugs or replace them.Also clean the battery , starter,alternator , engine block ground posts and any grounds and any plug in connectors on the sensors etc with a small wire brush, fine sandpaper and file.Check the air filter,oil and tansmission fluid and filter on it too.


Hope that helps and best of luck.By the way it sounds like moister or dirt in the gas system etc.
