P0030 Code

Gary Vansickle

Test Drive
I installed an engine I bought off JDM Auto.
Everything fit perfect but had to use injector rack off old engine because of orientation of fuel Line.

Got P0030 very quickly.
Engine lacks power - severely!
3/4 Gas Peddle to get up a small hill.

Replaced distributor, plug wires, spark plugs
Crankshaft position sensor, ground wires, fuel filter.


Took to Nissan
Gas pressure very good - they could not figure it out.
No vacuum leaks I think.
They check 3 injectors which were okay - the 3 easily accessible.
Rest are under Upper Intake they did not check.

Unbolted one exhaust manifold in case a catalytic converter clogged - no increase in power but very noticeable misfire.

Timed the engine today and got moderate improvement - no more backfiring at least.

Got Starter fluid - no Vacuum leaks

Googled everything and tried almost everything.

Any ideas or suggestions?

Think will pull all that reap off front of engine and see if timing belt has slipped
