Sounds like your car is in "limp" mode. I'd get that check engine light checked out with a scan tool. Maybe you have an O2 sensor out but I haven't heard of it causing your engine to go in "limp" mode. Go see your local dealer!Y2A said:Ok, nowadays, the check engine light comes on randomly and when I accelerate, I cant rev past 4k! Whats wrong? and How do I fix it? I have a 02 Accord SE btw.
