hey Scotty I have s question for my Pontiac G5. while i drive 60Km/Hr or more at a steady speed my rpm go up a few hundred and then drop back down to normal. it does this a few times then goes back to normal then does it again. So far ive tried spark plugus and a cleaning my throttle plate/body and MAF sensor. no check engine lights/codes. Thank you, Keep up the Awesome Videos.

on those, often that's a transmission starting to go out, notorious on those. Have a pro road test it with his dealer level scan tool and analyze the data when it does that.
