it sounds to me like you have a vaccume leak somewhere. autos are always more expensive to repair when broken and they are weaker in some aspects. if you are doing street racing(illegal) go with a manual. if you are going to be doing alot of moving the steering wheel(on the track or dirt roads) i would recommend having an automatic, it gets a bit difficult to shift, steer, and not hit things like trees or walls.
so manuals are tougher but you have to manually shift, and autos are weaker(not by much) but allow spirited driving without overthinking. if you race and decide to go with an auto you can do like me and buy spare autos with low miles. after you swap a few it gets pretty easy to do. and if you feel brave and know anything about how an auto works you can rebuild them fairly easily.
