One day, I was in hurry so instead of starting in the first gear as I have done everyday, i just started in neutral so the AWS would kick in. It holds rpm at 3000 for few seconds and when it came back down to 1500, I could feel little roughness. I let it warm up and drove off and i still could feel little roughness and felt it wasn't running as strong as before. I gave a ride to my friend who also owns a rx7 but he couldn't really feel the difference. I can't really tell if it is running different anymore. am i just too worried or should i look into it before the engine goes pop? The car idles and boosts fine. Thanks.

 

nobody?

 

doesnt sound like a problem to me if it feels ok now.
