Hey their, Im thinking about buying a lexus, although the guy says that it runs rough and has poor acceleration and he says the "check engine" light comes on interminttently............................... If you have any idea what this could be, any suggestions would be awesome.... I read in another posting on here that a guy had a eclipse or soemthing, and it was low on coolant....and that made it do something like that, but im not sure...just any suggestions would be appreciated..thanx guys (and girls ;) )

Ask him if its throwing a code, or ask him if he knows why its not running correctly.
