Car shakes and sputters at certain RPM.


Asked by Apr 19, 2014 at 10:10 PM about the 2004 Honda Civic Coupe EX

Question type: Maintenance & Repair

If I am going up a hill when I accelerate to maintain speed the car shakes and sputters when it hits around 3800 RPMs and I have to back off the gas pedal.  Honda dealer had me replace the solenoid and that solved nothing.  Need some help.

Check engine light on? Have auto zone read the codes. They will do it for free. Post code numbers back on here.


The check engine light is indeed on. I will check out Auto Zone. The dealer did do a diagnostic test and it concluded the solenoid needed to be replaced. Thanks for your help. Will let you know the results.


Went to Autozone and the code was P2646. VTEC Oil pressure switch low voltage.
