    Alfa 147, 156 & GT
    Hi I am having some issues with my 147 purchased about a month ago. All of a sudden while driving the revs drop to idle and I cant do anything about it. I leave it for 10 minutes and its fine again. Searched the threads in here but couldn't find anything. Happened 4 times so far completely...
  2. Stability on hard acceleration

    Alfa Giulietta
    Just got home from a 550km trip to a family wedding in the south west. I had it in dynamic mode and sport on the tct for most of the trip. On a few occasions when in 3rd gear behind a road train I gave it a boot full and it started to want to track all over the lane. Not real good next to one of...
  3. Additive to reduce black smoke on acceleration

    Alfa 159, Brera & 946 Spider
    My 2.4 had it’s dpf removed about 3 years ago. I have noticed that on hard acceleration it is now pumping out quite a bit of black smoke. Is this something that I am likely to be able to reduce with an additive? I tend to use the best quality shell diesel fuel so am surprised to see this much...
  4. AC and off-the-line acceleration

    Alfa Stelvio
    Hi All- New to the forum and a new Stelvio owner. So far I’m lovin’ the car and the experience! All of the things I was worried about, upon reading many complaints about infotainment, HK upgrade, etc., have not been an issue at all. One thing i’m noticing though and can’t seem to find any...

    Alfa 159, Brera & 946 Spider
    hi, I know it's Alfa's forum, but I have tried so many Fiat's forums and get not even a clue, but while digging the internet found some similar to my problem posts regarding AR so I decided to take my chance here. I have Fiat Tipo HB 2017 version running MultiJet 1.6 120hp. Since beginning it...

    Alfa MiTo
    Hi all, Not posted on here for a few years, not since I killed my beloved 159 ? Anyway, my Mrs has just treated herself to a MiTo 1.4TB (155). What a lovely little thing it is! So jealous! The first niggle is that on a few occasions the car has been very sluggish in second, with the power...
  7. 159 wobbles on acceleration

    Alfa 159, Brera & 946 Spider
    Hi all. I decided to take my 159, 1.9 JTDM on a lengthy journey on the weekend. During the trip, I noticed a wobble on acceleration, mainly in 3rd gear at about 40-50 mph. There's no vibration from the steering. It seems like something under the bonnet. Only had the car for a week and never...
  8. MiTo veird sound on a hard acceleration

    Alfa MiTo
    Hi everybody, I noticed a weird sound coming from under the hood on a hard acceleration (under engine load). This came first last autumn and has been audible since then.

  9. Car judders/jolts under hard acceleration

    Alfa GTV & 916 Spider
    When driving under hard acceleration (from about 4000+ rpm) my 2.0 tspark will judders/jolt and the ECU light will come on for a couple of seconds. The ECU is not storing any codes so I don't know what could be causing this to happen. She drives fine around town, it's only when I put my foot...

    Hi everyone, I've noticed over the past few months that i'm getting a pull to the left under braking and a pull to the right with acceleration. The tracking was done just before Christmas and i always keep an eye on the pressures. Additionally, the upper con arms we're replaced last year too...

    Alfa 159, Brera & 946 Spider
    Hi all, I've recently purchased a 07 159 3.2 V6 Q4 Auto. Car is amazing ? but my only concern is that when I accelerate quick from a standing start there is a vibration/judder from the rear axle. It disappears just as quick and there are no other issues once the car is going. Any ideas what...

    Alfa 147, 156 & GT
    Hello everyone, once again. Today I figured out that my GT is making an hissing sound while accelerating. It seems that it makes no strange sounds while idle, but it starts hissing from 1500 rpm on. In order to be more specific, I'll attach a small video to show you what's going on...

  20. Gurring noise on acceleration

    Alfa MiTo
    So i've been hearing this strange sound from the engine, I used to hear it when I rev about 2000. But today I noticed it while sitting idle and pressing the accelerator. It doesn't happen when just sat idle, only when pressing the pedal. Its like a deep growl from the engine with a metal tint...
