Hi crowd. Here's a rundown of my sitch. I recently replaced my VR
engine with another lower mileage one. My original had started to give
me problems(P0300) which I thought may be just spark plugs, was i
wrong. Turned out the timing chain had slacked off knocking everything
out of whack and possibly bending my valves. I decided to just swap the
engine for good measure. Now I have the newer one in, but I am still
getting a P0300 code. The engine will start and idle @ spec (625rpm+/-
50; 15+/-5 BTDC), but rev it up past 2G and the MIL will start flashing
again. I replaced both O2 sensors( not the CATS tho, one was clean the
other was chock full of sh*te, both now leak) but seems like the engine is
not getting enough air. Haven't been able to detect any air leaks and I've
followed the recommended procedure via Nissan Service & Repair manual.
FYI- I was checking the continuity from A/F B1 sensor to ECM and the
terminals do not match up to what the manual says.
