Massive missfire
« on: October 15, 2011, 05:27:08 pm »
Hello there,

Just been driving back home and gave it some beans, and the car hesitated, fluttered on boost, and now runs like a bag of rusty bollocks nails.

The engine shakes the entire car and the tiny 4 pot engine now sounds like a V8  :evilgrin:.

Plugs changed 2 weeks ago. Coilpacks never changed...

This is a pic of one of my coils next to my normal looking one. Does this look burnt out to you?




I rang Dave at PDT who was VERYYY helpful and I can't thank him enough for answering to an idiot like me, twice on a Saturday evening.  :drinking: :drinking:  :notworthy: He explained its likely to be a coilpack or a sparkplug that isnt tight enough..

Just wondering if anyone else has had a similar problem? And how they overcame it.

Nick

Very commom.  There maybe be a dealer recall on your coils packs which should get you a set of 4 for free, phone VW monday and give them your reg number and ask them if there any recalls on your car.

Cheers Nick. Just been outside to take a video...



I'm pretty sure VW said I wasn't down for the coilpacks :(

Sounds like mine when my coil pack was gone.

Did a fault light come on??. If it did get it scanned, if not make sure a spark plug is'nt loose and go from there.

I had a mis fire on my car shortly after fitting new plugs and it turned out to be a faulty plug.  Have you still got your old plugs to try and see if it runs okay. Failing that it will be a scan to see which cylinder shows the misfire or change all 4.  If it was me and the plugs were fine then Id change all four coilpacks as I think if ones gone then its reasonable to think the others may not be far off from going.

My cyl 4 always gets rusty, water always gets in there. Im sick to the back teeth of my car atm.

Well...

My exhaust light is always on due to a 3" downpipe recently being fitted.

However, when driving on misfire, the light will flash??  :chicken: :chicken:
