Well then...

Hey guys, new coils and plugs, pretty sure it's injectors, but am willing to take any other suggestions. Thanks !

ewicky · 12-16-2019, 06:50 PM

how new? did you try putting the old plugs and coils back in?

500 miles maybe and no I haven't

Soden82 · 12-16-2019, 09:08 PM

Looks likely that it's injectors from looking at that list of codes

clegg · 12-16-2019, 09:15 PM

Do know know what Index# injectors you have?

relative4 · 12-16-2019, 10:46 PM

4+ injectors going bad simultaneously? Mmm...
How long since your last walnut blast?

Exactly my thought! I would be looking into fuel deliver and O2 sensors. Or maybe misinstalarion on new coils and spark plugs. Or wrong parts? Screen shot is from JB4 so maybe some logs? Let's see....

relative4 · 12-17-2019, 07:43 AM

Did you have exactly the same symptoms before replacing the coils and plugs?

It was misfiring on old coils and plugs, then swapped it out, still had occasional cold start misfires, put some Techron thru the system made it a little bit better for few 100 miles but now it's just has seemed to given out. Wierd noise on startup as well I'll post a video here shortly

iqraceworks · 12-18-2019, 12:25 PM

Do you have any way to run a data log and monitor your fuel pressures? It's odd (impossible?) to have 4 injectors crap out all the exact same time.

I'm guessing you have a fueling issue....

Put in old coils, this is a cold start, let it run for about 5 minutes and now it seems to be running fine. But every time it starts in the morning it will misfire shake, give off a ton of smoke and a lot of fuel smell. Afr 2 is reading 20 on JB4 while afr1 is reading between 14-16

After your car sits all night.....pull each spark plug out in the morning (don't start the car first). If any of your plugs are wet, or smell like fuel.....you have a leaky injector in that cylinder(s). If they are leaking....replace them.

My assumption as well. Car drives fine after about 4-6 mins on a cold start with misfires and excessive fuel smell, but after things are warming up there's no issues.

BM3Rrrr · 12-19-2019, 06:14 PM

All these signs point to leaking injectors

Agreed, but 4 at once? I'd run 2 more bottles of Techron through it.

Any suggestions for cheaper injectors in the meantime just to run the car on stock tune and use it for daily driving ?

There is no cheap injectors for the N54.

I mean there are lower index's correct ? Don't necessarily have to be index 12 just for everyday daily driving

I guess if you can find a deal on used injectors yes. But for new parts there isn't.

Index 12 is the latest version. I wouldn't recommend swapping in anything other than Index 12, all previous indices were faulty.

Index 1

is very good, also, 5 and 7, but 1 is exceptionally well.
