Hey guys, I'm trying to find out if any of you know a specific way to tell if any of your fuel injectors are bad. I already changed out my spark plugs and coils, but my engine is still misfiring. I did not notice anything particularly wrong with my fuel injectors tho...
Any advice would be helpful. Thanks!

Do you have INPA or ISTA/d?

Chances are it's a VANOS solenoid or eccentric shaft sensors. Injectors aren't usually a problem on N52

What codes you pulling?

A bad fuel injector isnt impossible on an N52, but its so improbable you better be 100% sure before you end up down a rabbit hole.

It ended up being my crankcase ventilation hose. Pretty big crack in it, had my car running like crap.

Changed all 6 spark plugs and coil, along with the crankcase vent hose....car is running like new now

Getting a proper BMW scanner is the first step. INPA, Foxwell NT510/520, or Creator C310.

but I agree, fuel injector issues on the N52 is super rare. don't recall ever hearing about them fail.

Uhm.. No. Its definitely an N52, the N53 didn't even exist in 2006.

ahh... you're right. I was literally always under the impression that the 2006 330i and 530i had the N53.

The N53 did debut in 2006 according to this Wikipedia link, but looks like the North American market did not get this engine because of the high sulfur content in our fuels.

According to the ETK database the N53 didn't start production until March 2007.

Either way, it never came here and all 2006 330i (Euro models included) were N52s.

How did you manage to spot the ccv hose as the problem? Did you spray starting fluid around or get a smoke test? I'm trying to trace a persistent cyl 4 misfire on my 328i. Replaced spark, coil and injector but it's still there.

I realize that OP solved his issue by simply replacing crankcase vent hose (never said he had misfire codes, just said it was "misfiring" and "running like crap" ;-), but since he asked the question about testing injectors on N52 engine, has anyone used INPA to do that?

Apparently DME, Activations (Steuern), Injectors (DME | F6 | F1 | F1) will do that (turn off EKP first), but I've never done it.

ANYONE who can describe what the activation actually tests? Does it show if the DME actually caused the injector to pulse or does one have to listen with stethoscope for click?

Thanks,
George

scotty kilmer is an idiot that doesn't actually show you how to do anything, well, doesn't show you how to properly do anything.
compression fittings on brake lines.
going under cars supported only by hydraulic jacks
and everything with more than a PCM is overcomplicated garbage because he wrenched in the 80's and is completely out of touch.

I'm amazed he's not dead yet.

he advocates for improper repair procedures that are dangerous.

unless you think that compression fittings on brake lines are OK.

They're not, and a proper flare union fitting costs a whopping dollar more, oh, and you'll have to buy a flare tool for another whopping $20.

So saving $20 on your brake line job is worth using fittings not rated for potential brake line pressures and endangering yourself and others?
and that's why he's a moron, and you are too if you believe half the shit he says.

you see any jackstands in that video either?

what about this one, where he compares DOD engines to variable displacement

completely un related.

what about this one, where he says that new refrigerant is dangerous,

you know that R134 burns too?
so does R12.

he's a clickbait out of touch moron.

I agree, the guy generalizes about everything. His mantra is: " Japanese cars are good, all other cars are unreliable. Toyota is the only car to buy. " He never mentions how many good non Japanese cars there are, and US and German cars were the first to bring many innovations we wall take for granted, not Japanese cars.
