  1. Constant Misfire on 1.4 TB MA (2010)

    Alfa Giulietta
    A couple of months ago I started getting intermittent misfires, now it's constant. I get a load of errors on starting the car - VDC Unavailable, Steering Corrector, Hill Holder and the engine is vibrating heavily. Also getting quite a bit of smoke from the exhaust. I only have basic...
  2. Best spark plugs for 75 2.0 Twin Spark & slight misfire issue

    Alfa 75, RZ, SZ
    As the title suggests, what would be a sound choice for spark plugs in my 75 Twin Spark. They were changed two or three years ago so it can do it no harm to change them again. Was thinking of NGK or Bosch. No need to spend silly money! Also, when driving at about 40-50, there is a little...
  3. Electrical Gremlins (including misfire)

    Alfa Giulietta
    After having my Alfa (2010 1.4 Multi-Air TB) for 18 months now with no real issues, over the last few days I've had a couple of warnings on the dash and misfiring. Thursday morning I got a brake pad warning light (pads and disks were changed in January). Anyway, that went away when I next...

    Alfa 164 & 166
    Hi all I've a 2001 166 2.5 v6 cf3, and it has developed a misfire. It started one morning, very lumpy at idle, but eventually gone, next day the same, but never gone ever since. The idle is stable but its clearly lacking a cylinder. Should point out the car is converted to LPG and onloy...

    Alfa 159, Brera & 946 Spider
    Hi, a second time Alfa owner seeking your wisdom. Last was a new 02 156 TS SW which I loved until it lunched a valve... LW02LXL are you still out there? This lovely 07 Brera is everything I hoped for but there a couple of little niggles that I'd like to fix. I've done a bit of forum searching...
  7. 2.2 misfire investigation!

    Alfa 159, Brera & 946 Spider
    Hi all, So last week I posted about a lumpy start and misfires with my 159 2.2. I’ve managed to rule out a faulty MAF and now I have the cool pack, spark plugs and injectors to check. In terms of removing the coil pack to get the the spark plugs, apart from unplugging the battery, is there...

  14. Anybody had a P0301 on their V6?

    Alfa GTA
    I though the GTA had been behaving too well recently... Randomly threw up the MCSF and a P0301 code today which I understand is a misfire on cylinder 1. Symptoms are very lumpy idle and pretty poor performance all round. Managed to get it home but just want to make sure that I'm doing the right...
  15. 2.4 JTDm poor starting and misfire

    Alfa 159, Brera & 946 Spider
    This topic has been covered a number of times but worth starting as a new thread as it often comes up. Like an idiot I spent a year tracing this fault which those of you in the know will instantly recognise as swirl flaps. I was sceptical that it would be the flaps as they apparently only cover...
  16. 1.4 TB misfire

    Alfa Giulietta
    Hi Guys. Just a tiny issue. I have a 2015 Giulietta 1.4 Multiair TB TCT. On cold starting, for about ten seconds the engine runs on about 3.5 cylinders. It goes onto all four after just a few seconds so it's not a big problem. Any of you technical wizards out there have a clue what the...
  17. Misfire when cold

    Alfa Giulia
    Hi all, my 2.0MA has developed a misfire/chugging when cold. It only lasts for 10-15 seconds and then clears and runs perfectly. Brought it back to the dealer 2 weeks ago who experienced it on a test drive, they updated software and it seemed fine until today when it happened again twice. 5 mths...

    Alfa 159, Brera & 946 Spider
    Hi. I own an Alfa 159 tbi with prins dlm 2.0 gpl. From some time I've started to have misfire. This happen only on cylinder 3 and when I require power (press down the accelerator). Some rare case the car response correctly (no misfire, no hesitation). I hope this means that injector and...
  20. GT JTS misfire

    Alfa 147, 156 & GT
    I've been trying to sort a misfire on cylinder 1 for a few days now. Because I had previously needed to change a coil pack to fix a similar fault on cylinder 3 a couple of years back (and because the JTS famously eats coils) I tried a new one. No joy with that. The fault which had at first...
