engine Rev
but it was a 1990 F-150 XLT lariet with a 302 and auto trans.
I had this problem for a while until i sold it. but When the truck was sitting still in park and at idle it would run fine then after about ten minutes or so it would to to rev up high and and low high and low until it finally would clear up or choke off.
What could have caused this? Like i said i dont own the truck anymore but i would just like to konw.
Thanks
