the other day i was driving my 95 honda prelude 2.3L DOHC and about 30 min into driving i felt two little jerks when stepping on the gas...the Second time i felt it I pushed the gas down and the rpms or speed didnt go anywhere. I had similar problems when my alternator got unplugged but the check engine light came on..... I pulled the code and it was 4 long blinks and 3 short blinks....
---O2 Sensor

Would an O2 sensor cause that problem though?
