i have a stock 1990 nissan 240sx 5sp 2.4l. It was passed on to me from an uncle who no longer needed it as a 5th car. Its all good and all but there are a few problems... The car shakes while im stopped at a red light, the car does not go past 5000 rpm (this one is the weirdest), and something seems to be wrong with the stand-by power (the clock and radio memory dont seem to be holding up). I do most of my repairs but im no expert... but i know there are plenty of you in this community... YOUR ADVICE WILL BE GREATLY APPRECIATED! Thanx
