New to these rx7s and my new vert I just picked up Friday isn't acting like I've heard they should. I know its supposed to start and go to like 2500 rpm for 20 seconds but mine does it for maybe 5 seconds then will die if you don't touch the gas. Once it gets moving and the engines warm its fine but when its being started up every morning it does this. Any ideas?
