Engine Mechanical problem
1994 Nissan 300ZX 6 cyl Two Wheel Drive Automatic 57K miles

After driving for a good warmup 15 to 20 min. it is now idleing faster than usual. I had the o2 sensors replased last year and all the injectors are new. I am machanically inclined to do basic work but prefer to have a pro work on this car. What Can I do.
