My 92 sentra resently developed an idle problem. When starting cold it
runs fine for about 20 seconds and then the idle dorps off and it
usually stalls. When warm, it will idle very low but will often die if
not helped along. If I have to stop quickly, it usually dies. I had a
fuel injector go bad last year and I thought that I may have had
another bad one but, last year I could tell the injector was bad by
looking at the plugs (among other things). This time all the plugs look
the same. I've checked vacuum, egr, wires, etc.. Any suggestions?

check the power going to the injector-coz resistance effects other
injector/leakin

Clean your throttle body and idle air control valve.

Have you checked the engine codes?
