Z32 POWER BALANCE TEST

[brian300zx]

What’s up guys so I was doing the basic “power balance test” on cylinder 1 in which I just installed a new injector.. so the car isn’t running like when it was when it had a bad injector as those of you who have experienced this know it’s horribke Car sounds like a lawn mower. Anyways after I installed the injector I did the power balance test and there is no difference when I pulled the coil connector... but the car isn’t running bad I’m just really confused. Yes I can hear the injector clicking l. And I’ve tried different spark plugs but still don’t notice the difference. Could it just be low compression?

Definitely check compression and leakdown, also check to see if the sparkplug is wet, often when replacing an injector people will pinch the o-ring and cause the cylinder to washdown (due to fuel constantly leaking in).
