I did some quick searches and didn't find this particular issue, although I may not know exactly what to search for. Anyway last week the car began revving very high during idle. As soon as you start the car it will rev up as if you're giving it gas in park or neutral (it's an auto), the rpm doesn't seem to go up and down its just a steady high rev and loud. Once you put it into drive or reverse the rpms will seem to drop and it quiets down, however I did notice when driving it's accelerating slightly at around 25-30mph even when not giving it gas. I didn't drive it too much like this for obvious reasons. Almost feels like the throttle is stuck but it I looked at it I didn't notice any obvious issue with it. The car also had an aftermarket cruise control put in, sometime in the 90s probably, it hasn't worked in some time though and I wasn't too concerned with getting it fixed. Thoughts? Thanks!
