Having problems with your 2003 Honda Civic ?
Installing 2004 Honda Civic Lx , 5spd. V-Tec motor into a 2003 Honda Civic Lx, Automatic with bad motor. There is one connector coming out of engine wiring harness by intake manifold and pulleys. The old motor is gone so I do not know what sensor is not used on the V-Tec motor? Also, what effect will that have on the 2003 engine controller.
Its probably has to do something with the automatic transmission with sending info to the engine to adjust when needed to shift.
