Question type: Maintenance & Repair

1986 300ZX Turbo. Finally passed smog, had problems at low speed, ran rich. Now, it
idles rough, and actually died a couple of times. Never had this problem before. New
battery, and starter put in a couple of wks before. Any ideas?

Check air filter and clean throttle with throttle body cleaner spray. Replace fuel filter if have not done so in a while also add fuel injector cleaner to gas tank.
