Engine Performance problem
1990 Nissan 300ZX 6 cyl Two Wheel Drive Manual 115000 miles
I have a 1990 300zx with 115000 miles. Just recently my car started to loose power and started bogging. I filled it up with 94 octaine for the first time in a long while. When I first get into my car and start it, it drives great for the first 5 min down the road then it randomly starts bogging down expessially in low rpm's and relly hesitats when getting on the gas. When I get out of the car it smells like pure gas. Could it be my fuel injectors? Or the different octaine? Oxegen sensor? Please help!
