Take to a nissan tech this sounds like a bad tps sensor throttle position sensor or a cruise control issue . Your problem is likely to serious to deal without a code reader an having the vehicle in front me. Think of safety first here or a accident.

I have 1990 TT, new injectors, new air filter, Idles at 2000 rmps, hesitates when I depress the gas pedel,but will spin up 2500 rpms then cuts out, any ideas?

disconnect the ecu for about an hour to reset these to the makers default setting, also sounds like the maff sensor has broken down, i.e computer tries to put to much fuel in and not enough air! have you also replace the fuel filter?

I am thinking of weighing the option of keeping it or selling it

if you like the car, and the rest of its in excellent condition, then fix its rusted under neath, paint bad, interior bad, then NO. try to find a low mileage newer engine. I dont know Nissan that well, but didnt the MAXIMA use thes same engine. if so, there a lot to choose from. a salvage yard should be able to tell you what engines will fit. I would get one from a MAXIMA if at all possible. older mature drivers, ect.

300zx erratic idle 1993 n/a

Your Idle Air Control Valve is at fault. These never set a code when they fail and they always fail.

Check this item out on eBay.

They aren't usually this expensive so search the net and you should find a much better deal.

You shouldn't need to worry about the gasket when replacing this. They usually don't tear and stick to the manifold. If it does tear though you should replace it
