My 2001 Honda Civic Hx has been acting very strange recently. When I start the car, and put it into drive, it jumps HARD and the RPM's drop very low, almost like it is going to die, but it doesn't. I do need to mention that I just got the front and top left motor mounts replaced and the motor mount in the rear by the automatic CVT transmission needs to be replaced as well. And also that my check engine light is on and it reads P1167 which is supposed to mean that I need an oxygen sensor replaced. The check engine light came on immediately after replacing the front motor mount. I really need help with these problems, and any advice would be greatly appreciated. Thanks in advanced! -Kevin
