Hello I have an 1990 300zxtt. I've been having problems with it lately. Everytime I take off, the car shudders. It feels like the power is coming on and then kicking off. This only happens when I accelerate, if I keep it at an steady speed it's okay, but what's the point of that. It does this on any temperature. I just gave it a tune up. You guys should know trouble shooting is really not an option when your strapped for cash so any advice, suggestions is more than welcomed. THANX!! -300zcargurl
