This is a motor I got off JDM auto
After install it has very low power and horrible gas mileage.
Kept throwing P0030 misfire code.
Put on
New Distributor
Plug Wires
Spark Plugs
PCV Valve
Crankshaft Position Sensor
O2 Sensor which was bad
Timed it properly with a light
Still threw the P0030 code
Decided to check timing belt, right side camshaft gear was off one tooth.
Adjusted and marks line up perfectly every time after a few manual rotations
Now it runs worse, ECM keeps moving the idle up and down.
All the wire harnesses fit perfect.
Engine came with alternator and power steering pump reversed hence it was the same engine but probably off a different Nissan Model
I will do compression test but starting to think the ECM is not compatible,
I did disconnect both exhausts at the manifold to make sure catalytic converters were not clogged - no increase in power
