J30 Engine Problem, please help!

[kevinmkc]

Guys, I need your experties... I have 93 J30 with 220k miles on it. (yah, it served me good all these years!!!) The car was running good as usual but at the light, I noticed it idled funny. Idle went up and down, up and down.... It went down to the point where the engine almost died. Luckly it didn't die and I was only one block away from my house. I got home, put the transmission on P, and idle started going up and down again..... I turned off the engine and when I try to restart the engine, it won't start! I never had any problems with this car, except I had to replace 2 fuel injectors...(besides usuall maintenance, timing belts....) Any help will be very much appreciated!!! Thanks guys.
