	 2007 Mazda CX-7 Touring 2.3L Hesitation, Bogging above 2000rp 
		
		The car acts perfectly normal until its under load then above 2000rpm its bogging. changed timing gear , chain, etc . concerned about either turbo issues or the lost communication code causing it to go into limp mode but noengine light remains on.
