truck revs while driving
Hey guys the past couple days my trucks really been buggen me. It doesn't do it but every now and again sometimes more then other but when I'm driving down the road it'll seem it looses power and my truck will rev up about 2 or 3 hundred rpms. It'll go up then down up n down. But if I put pedal to floor it'll think about it then get up and go. Any idea what my problem could be ? I don't get it.
Any help would be great. Thanks.
