How do I fix my Subaru Legacy 1992 AWD from nearly dying after first start up ?

Question

I have a problem with my Subaru Legacy AWD 1992. When I first start it (cold or hot day), it seems to start ok. Idles high (1500-2000rpms) but then lowers when car is warmed up to about 900-1100 rpms. I drive it to the store and go in for about 10-30 mins and come back and start my car and it nearly dies (idle bounces real low and high until stable) or sometimes even dies and have to turn ignition more than once. I'm afraid one of these days, my car won't start back up again. My battery doesn't seem to have any corrision on it and is pretty clean. I would appreciate it if someone could give me an explanation on how to fix it or what I should do to get it fixed because sending it to the shop not knowing what's wrong usually results in spending more money (on a tight budget). I'd rather fix it myself if it's not going to be real hard. Need to get it fixed A.S.A.P !!! Any helpful answer is appreciated, Thank you.

Sounds like you need a good tune up. New plugs! timing checked ! New air filter! New fuel filter! ! Can try Trechron injector cleaner works pretty good if not too bad!
