No, it is not normal for a newer car to idle and shake rough. I have had the same problem with my car and all it required was a tune up and a change of the spark plugs. I work for General Motors as a Licensed Mechanic. I encountered a sitution on numerous occassions where one of two problems existed. First, if the alternator had been replaced and the harness (sensor array) had not been properly re-routed, vibration caused the injector set harness (back left of the fuel rail), to rub through on the alt. mounting bolt causing a short to groung on one of the injectors resulting in a misfire, excess O2 down stream, compensation through the O2 as a lean condition, and ultimately the IAC trying to compensate with increased air. The second most common problem resulting in over idle speen a vacuum leak into the intake. Either through the crank breather vent or failed phlenum gaskets. Either condition tends to flip the SES with a 'high idle' or 'rich mixture' fault.

You didint mention for what engine, and that's important because every engine has its own correct idle but to give ya a rough idea, the cold idle is usually 950-1000 RPM and warm idle is usually 850-900 RPM!

My 1996 Neon 3-speed auto transmission RPM shift from 1000 to 1500 when idle N or P. But if I change from N to D or P to D RPM is back to 1000. Anyone know what's wrong?

Simple, in D or any other forward or reverse gear you are putting a load on the engine by activating the transmission. N or p are neutral gears that put no load on the engine and that is why you can take your foot off the brake in either one. The question is what is the normal idle rpm of your vehicle? If it is out of range then it must be adjusted.The normal idle RPM of Neon is 1000. It just went up to 1500 when I stop at the red light yesterday. It was 1500 rpm on both N and P. It's never been like this. I think something is wrong.
