Yes Engine 1 gets you stuff like cam sensors and flap motors, Engine 2 gets you some other sensors, but all the misfires show there.
Just out of curiosity, are your dividers in or out of the head?
Not sure about the TB reset, maybe someone else can chime in.
Ed
Do you mean the blanking plates above the valves with the dividers?
I’ve left them out with the re-install of the intake.
now i’ve seen your topic i think i maybe missed a bad alignment of the spacer… i think i’ll just pull the intake again this weekend just to check what’s going on… this thing is driving me crazy right now!
I can’t drive it on a regular base since it requires the room to hit full throttle and rush hour traffic won’t let me…
I’m done with my girlfriends Opel insignia with 140hp diesel engine 
It’s kinda hard to mess up the alignment of the spacers and the gaskets.
Misfires after an intake removal tend to come from a leak at one of the mating points. Check your Y pipe and your intake manifold bolts.
Also make sure to double check the complete VAC and PCV system. Those are two other big spots for vac leaks. Any vac leaks and you’ll see an issue with misfires and low rpm hi load.
You can always check your LTFT data to see if that shows signs of a vac leak.
what do you mean with LTFT data?
all bolts are new and my Y pipe is new as well with new gaskets…
i will recheck the PCV but this is also a new unit.
I did find it odd how hard the vacuum pulled at the oil filler cap…
Long Term Fuel Trim - measuring block inside VCDS. I do not know which block it is, but you should be able to find it on the VAGCOM site.
Ed
Long term trim:
bank 1 is -3,1%
bank 2 is -2,3%
From the first things I found this seems normal…
Can I jump to conclusion that I am facing an engine drop?
Another thing I saw is that there is an option fuel system 1/2 status where it says closed loop using o2 sensors in green so does this mean they work?
Fuel rail pressure (rel): 3400kPa rel
Is this a good value? I do understand my engines but I’m new to the computer /programming part
So, still no sollution here and it’s driving me nuts.
The car still misfires under low (almost stationary) load and when stationary.
Misfires occur on cylinder 1/2/3/4/5/6/7/8 never on 9/10.
If i am at a traffic light the CEL starts blinking after a while so i know this is the time it starts misfiring. Sometimes it gets solved by itself but most of the time i’ll get EPC and CEL telling me i’m no more running on all 10. Just a quick engine off and on will solve this.
If the blinking starts and I put the car back in neutral and rev it af few times the CEL engine light stops blinking so the misfires stop.
If i’m driving hard or not too long on constant throttle everything is OK, engine runs smooth and strong.
BTW i changed: spark plugs, injectors, coil packs, all intake gaskets, the connecting part from throttle bodies to intake, PCV an HPFP’s. Pulled out the JHM spacers for now so i get the car completely stock to search the solution here.
One thing I noticed is that if you check the fault codes i read pressures from 1000mbar to 1010mbar when misfiring at idle…
I would expect these readings on full throttle. Since the throttle valves are supposed to be closed on idle i would expect a lower pressure here or am I wrong?
The miss fire monster is terrible.
If the car misfires often get your vag com ready. If the misfires start make sure to have the engine module open to the code section. When they start hit clear codes. If the misfires stop and don’t come back for a little bit. There are good indications this would be from a bad 02
I’ll check this as soon as I can!
I can’t justify dropping the engine and changing the o2 sensors without being sure that this is the culprit…
So today I checked the misfires as said above.
But when they occur and I do a reset they immediately come back.
I’ve rechecked the valves this weekend and they seal well… So I can’t blame it on leaking valves to small pieces of carbon.
I guess my best shot is have another view at my vacuum system to check for leaks or broke backpressure valves.
Since the faults don’t go away with a reset but the CEL keeps blinking I’ll rule out the o2 sensors for now.
I can’t imagine it being compression related since the car has it sometimes but not al the time…
Have you tried a smoke test yet?
Ed
I’ll make a smoke tester tomorrow to try a smoke test 
Finally had the time to do a smoke test today…
I found a leak at the connection of the pcv with the lines coming from the valve covers.
I’ll fix this tomorrow since today is a national holiday and the shops are closed. But I highly doubt that this leak can be the source of my problems 
So I fixed this leak but the car still misfires. Now this seems strange to me but the car seems to start misfiring when put in D or under some load of the transmission.
When I leave it in P or N it goes perfectly well…
Van someone shine a light in this
The only thing of note is that you are putting pressure on the power train when you engage the transmission.
So you are still getting all the same codes as your original posts?
Ed
Yes codes are still the same.
Intermittent random misfires and misfires from cilinders 1 to 8.
Only under low load…
So to stop the misfires you have to feed more throttle/revs or let the engine run free (park or neutral)
OK i’'m out of ideas…
I made an appointment in a month with a specialized shop, they’ll do a transmission flush and troubleshoot the car.
This goes above my understanding…
