1992 Nissan 240sx KA24DE-T >> rough idling / revs diving and stalling the

[astluis]

I'm runnin a 95 KA24DE with a mild turbo setup. While driving around I have found that I have to control the throttle during deceleration and baby it down to idle or else the revs keep diving down until the car stalls. This isn't too much of a problem for me because I simply downshift and match revs and it eases the revs down well enough to where it will idle fine. I actually think this may be because of the fuel regulator dropping its rate whenever the throttle is suddenly closed at mid-range RPMs.

However (just today in fact) the car has started to have issues with the idle stumbling as I'm sitting at stoplights/signs. I think perhaps it was just low on gas. I have to keep an eye on the miles because of a faulty sensor in the tank and I may have run my gas down to the last of the fumes so it wasn't getting the fuel it required to run steady.

I have also started hearing a light rattle while the car is idling. It seems to be coming from one of the wheels. It may not actually be a "rattle" persay. I may just be paranoid because of the trippy idling.
