got a 55 gti and recently under hard acceleration it misfires a little it feels like its holding back and the engine light flicks on/off
amd stage 1 map
milltek tbe
forge intercooler/dv
the spark plugs are around 3k old and the coil packs a week old
any ideas?

You need to get the car scanned for fault codes and even some live logging when the problem occurs.
-
This might sound weird...check your oil. Mine has had a mis-fire recently, shortly followed by the oil warning light. Its not done it since topping it up. Failing that logging will help

Still cant suss that out Chris lol
new N75 goes on Monday if you still want to try the one that is on now :happy2:

Any closer Rob? Master of misfires

Atleast i'm not alone then in my misfire adventures :pomppomp:
Having it scanned and looked at by AMD on wednesday morning so hopefully get the bottom of it, am i right in thinking there was somebody on here that had an AMD re-map with this problem and switched to REVO and it cured it?? :confused:
D-- a- v e.... :driver:
-
Saw something yesterday where someone wasn't impressed / had teething problems with amd map and switched to REVO
-

yes my missfire apprentice :laugh:
its going back nect week , they want it for a day and a half to change my spark plugs and coil packs ?
now i dont want to tempt fate here but they do know where my engine is on my car , dont they?
considering i dont have an engine cover i was thinking 40 mins tops to change them al out , so god knows why they need it for so long.
not long now for you Mike , i bet this weekend is dragging on?

Nope not once since, the last time was the day before I came to you. It's a mystery :laugh:
-
i joined this club today mine feels like either a slight boost leak or plug issues
-
Forum definately needs a missfire section :sick:
-
New spark plugs fixed my miss-fire issue under load/boost...
Who did them, are they torqued correctly and correct make grade...

Strange one?
I have started to look in to these intermitent miss-fires / Hicups a little more.
-
had mine scanned and it said misfire cylinder 1 and 3,
but the plugs are around 3k old and coilpacks 1 week old,
might invest in some new plugs from vw was told there around £60 for bosch platinum

New plugs solved mine as well.
-
But if you're seeing a missfire fault it's more likely coilpack as that's where the fault signal comes from... spark plugs didn;t show a fault on mine...

I think you are correct.
My missfire problems with my spark plugs have shown a cel but only when they are shot to pieces.
normally i just get the stuttering when trying to put the power down , but when they are nearly dead i do get the flashing cel , and if i carry on trying to put the power down i do get the full on cel :sad1:
funnily enough i have only had 1 coil pack failure and that was a full on cel , thats not to say the other packs are not on their way out.

Or buy from a local Bosch dealer for £3.20 each, exact same part as the main dealers sell for £12+
-
So far so good :happy2: had my plugs changed today and the car feels like its old self again, time will tell but so far no more misfires or stuttering :drinking:

With you being stage 2+ you may need a step colder plug than standard. When increasing the power there is more heat in the engine and the spark plugs gets too hot and the tips or core burn out. Id opt for some plugs in the 8 heat range as they will cope with the extra heat better.
-
Plugs also fixed my occasional stutter/misfire. Infact, it also fixed 100% the shakes I had at idle and I feel like I've had a real boost in power and torque. Old plugs looked shocking which makes me wonder if they are the originals and VW never changed them when they should have. I bought the OEM NGK plugs which a 1 stage cooler. So far I'm really pleased, car feels brand new again :happy2:
-
just baught 4 new ngk spark plugs from alan day vw £54 fitted them and the car runs like new :happy2: :grin:
-
glad its sorted mate :wink:
its a common problem hence why so many replies about changing plugs as the cure.
but you could have done it yourself for under £25!
