Could be a camshaft potion sensor. Does it happen when you are under a load when cold. Like going up hill with the throttle about a quarter of the way depressed. Hard to say exactly with limited information. Any other info or symptoms would be helpful in diagnosing this issue
It runs beautifuly till it reaches operating or near operating tempreture...a friend of mine suggested that it might be the eletronic shifting valve body..I would like to know if this is a fix for this problem cause the part is a bit pricey
