i just bought 89 240sx 5speed SOHC all stock 2 days a go. the car drives fine through all gears on the street and highway BUT if i try to push it i got fuel cut around 4000 to 4500 rpm in 3ed,4th but 5th it cut around 3000 rpm. Also it get weak after 3500 in 2ed. I smell gas in car every time i drive it. i tried to find out what the problem but i couldn't. some one told that ECU has governor or limiter in some of SOHC (KA24e).

any advice would be great help.

thank you for you help.
