friend of mine has a 1992 integra rs stock. he says on hot days it has trouble starting. he says it cranks but wont start. in the cold it's alright but hot weather wont start right away. i don't know what the problem is with it. he says he's taken it everywhere and no one seems to know. i just wondering if anyone has had this problem and could tell me what it is so i can tell him?
