gota 2004 Civic SI(K20A3). got in the car last night after church, pulled out the lot and went to take off, ... car revd fine to 4k then it startd acting like it was bouncing rev limiter.. shift to next gear, its fine til 4k then it starts jumping again and wront go past that point. clutch in and tried reving and its doing the same thing. .. got fuel from same place as always never had a probelm... any ideas?

 

is your check engine light on? if your o2 sensor dies while running it can get stuck reading a high af ratio & everytime you get on it you'll hit the rev cut imposed by lean protection

 

Does the VSS work?

 

VSS?

 

vehicle speed sensor

 

Not the O2 sensor... i stopd after work and put 10$ gas in today because the gas light came on. left the parking lot, it was fine for 15 mins, called a buddy told em about it...then it startd ****ing up again... next idea? and yes the VSS is working

 

Any mods? Any service etc performed lately?

 

what does you oil level look like?
