My 92 eagle starts a little hard but idles and runs great when cold lacks some power but once it warms up it wants to die when i let off the gas after accelerating even though it will idle fine just a little low and it is almost impossible to start when at normal operating temp i got it with a head gasket leak and i fixed that ive tried everything but checking the turbo can that have any affect on this

The INFAMOUS DSM Hot Start Problem
Here are a few things to try:
1) Block off your EGR valve. Sometimes these fail, and when they do, this is what happens.
2) Change your vaccum hoses, especially the one going to the fuel-pressure regulator. Sometimes this one leaks and creates problems for the FPR.
3) Change your plug wires. I'd use some MagnaCore wires. They're less $$$ than the stock ones, and they're 8.5mm opposed to the stock 6mm. The stock wires are no good, especially when raising the boost.
4) Clean your throttle body REALLY well. Make it spotless, including both sides of the throttle plate.
5) Clean out your intercooler. Do this by taking it out, dump about a gallon of gasoline into it, then shake it around and dump out. Repeat process until gas coming out is clean.

Not an uncommon issue for one to idle fast while cold but , 2000 rpms is a little higher than normal. May want to check the engine coolant temperature sensor for proper voltage and the coolant level. Also, check for small vacuum leaks around the throttle body gasket.
When I was building my 97 GSX, I ran into this same problem. I found that I had a bad vacuum leak. Of course, this was after I had done a tune up, changed the fuel pump, injectors, etc.
Let it warm up without driving. Set you idle a little higher by adjusting the idle screw on the throttle body to about 2500 or so. If it does the same while sitting then you can start checking for leaks. Acquire a can of starter fluid from your local auto store. Spray in different areas, short burst (DO NOT blanket the engine area) around the engine compartment, 1 at a time. If the idle changes then returns that is the rough area of the leak. Look around that area and see what it could be. Then you can start fixing the problem.
If not then you will need to get a vacuum tester. You can rent them (Autozone, Advance Auto, NAPA) or find a shop (though that would cost you more) that could check it for you.Follow the directions on the tester.
definately air leak. mine is non-turbo, but has a large crack in the intake tube. Course, i'm a little lazy, so I just unplugged my airflow sensor and set idle up a few hundred to get rid of most of the lope. Let me know if this helps :)
probably oil, it may be too thick when it's cold but once it warms
up it liquefies and your engine runs smoothly. you could try changing oil, I'm
guessing if you have a high performance oil the chances this is the problem may
be greater since high performance things are usually geared towards working well
when everything is hot
