The only thing I can't confirm is if the Injector pulse width changes to make up for the cylinder thats shut off. Let the test run then go to the 'Summary' tab to see the result in detail. When the above is set correctly go to the main default screen by selecting the 'Test Results' tab-> The select the 'Start/Stop tab on the top right-> Press Start.

When all of the above is set then select 'Save' then every time you open the program those setting will be used unless changed. (You can check the 'Power Balance' box but I am unsure if it makes any difference. (Cylinder off and cylinder stabilization should be bot 9 seconds). (Under RPM Adjustment turn the dial all the way to the right till you see 200) (This is to hold the AAC wide open (100%)) Make sure the values on your screen match those below then press the 'Save' button Start up OBD Scan tech (Nissan)-> Go to the Power Balance button on the bottom left of the screen-> Go to the Options tab-> Timing according the ECU seen through the Consult is set to 15* Before Top Dead Center.Įnough about my car here is how to set up the power balance test so you get good results: All the spares OHM to at least 7 OHM's and the spare harness has continuity to all connections. There is a leak on coil packs 1 and 2 but I need to make the time to reseal them, I have 8 used spare coil packs and one used harness for the right side. The spark plugs were changed last year with OEM NGK standard 5 heat range, Gap may or may not have been checked to make sure its correct. I am worried about using Marvel Mystery Oil because I haven't heard many good things about it. I have tried BG Quick clean thats put into the engine oil and run for 15 minutes a couple of times but thats has yet to fix it. I never did a oil pressure test but on of the HLA's on the left bank possibly #7 cylinder is clogged and makes a noise. I never did a compression test but the engine was rebuilt at 30K miles at a Infiniti dealer (Not back in Japan).

Injectors are a couple of years old but I have no history of a BG power flush, just BG44K and Redline S1 along with ISO Heet. So we can confirm that the intake is clean and I have no vacuum leaks not a big one at least because at idle I get 20' Hg (~650 RPMs). I cleaned the Throttle Body Last year and the EGR and the plenum is fairly clean (No build up in the EGR port on plenum). I last semi cleaned (Half a**) the AACv two years ago I think (Can't remember) but in that time it got fairly dirty I would say to climb so high. Today I installed a clean Auxiliary Air Control valve/Idle Air Control Valve and the Auxillary Air Control valve duty cycle went 30% down to a normal 10%.
