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!

Thanks, Cameron

Why would you want to put the 350 engine in the Z...?
