I have a 1983 280zx Bought a year ago. Always ran like a dream till early this week. As I was driving and car was good and warm it started to stutter on acceleration after stops. I got to my destination and turned car off not thinking too much of the acceleration stutter. After 10 mins I went to start car, it turned over started and stuttered pop and chugged then stalled out...it would not start again until it was totally cooled down. I replaced fuel filter, coil spark plugs and wires. It then ran great for about 2 or 3 hrs until the same old stutter came back and the same engine dieing and not starting. Any ideas?

SOURCE: stutters when it has warmed up it has been doing this for 6 mth

your throttle body is carboned up have it cleaned out. this should fix your idle problem .

SOURCE: i have a 93 altima

this year model is notorious for fuel related probs...check the remainder of the fuel system, injectors, and the fuel pressure regulator also verify that the fuel pump is actually running and getting the correct amount of power to the pump itself..... it may not be bad just not getting enough power

SOURCE: 1993 altima will crank but will not start..

replace the distributor oil is leaking into the electronics of the distributor and shorting out pull cap back off and look and see if oil is leaking out

SOURCE: car ran fine drove it

This sounds more like a crankshaft position sensor. When they start going bad they will work when vehicle relatively cold but fail when hot.

Hope this helps, it it does please leave feedback and vote Thank You and Good Luck

A throttle positioning sensor or idle sensor can cause these problems, low fuel pressure can cause these problems also low fuel pressure can be caused by a faulty fuel pressure regulator.
