  1. Lurching when accelerating at speed or cruising at speed

    Alfa 159, Brera & 946 Spider
    Driving on motorway/duel carriageway at 70ish, sometimes feels like someone's stamped on the brakes for a second, can happen when in cruise control or not can happen when accelerating from 60, never seems to happen when driving round city. I'd guess it's fuel related like rail or fuel pump...
  2. Could a worn engine mount/stabiliser cause vibrations when accelerating?

    Alfa 147, 156 & GT
    147 Ducati Corse 1.9JTDm I've had vibrations when accelerating hard in anything above second gear since I bought the car. Recently had both spiders in the CVs changed and expected that would fix it, but it's just as bad. I've also experienced quite a strong shudder from the engine when...
  3. Not changing gear if accelerating faster

    Alfa Giulia
    Hi all, Sorry, a complete newbie to both the car and an automatic. This is likely due to my lack of knowledge on how an auto box works. If you put your foot down even remotely I thought by releasing the pedal the car would change up a gear? What seems to be happening is I put my foot down...
  4. Strange noise when accelerating

    Alfa GTV & 916 Spider
    Hello. It seems like I have a problem, there's this weird sound coming from somewhere front left of the car (GTV V6 TB), I'd describe it as a loose belt kind of noise, like it's clanking. It's not ever present, just seems to appear when giving the gas pedal a squeeze, mind you, the car can be...

    Alfa 147, 156 & GT
    Hey Guys, Need your help here. Recently my 147 2.0 TS has started faltering, initially it was almost in any situation, during acceleration and also on idle. Around 50 KM since I was noticed for that issue, the "Check Engine" dashboard light has turned on, I've checked and it was says that...
  6. Steering wobbles when accelerating from 70+

    Alfa Giulietta
    Hi. Help required please. On my Giulietta 1.4tb, the steering shakes when I accelerate from 70+. 0-70 and anywhere in between is fine. 70+ is annoying. I changed the nsf driveshaft thinking might be the inner cv joint but no luck. Drives same as. Dont really want to change osf for fun. Any...
  7. Hesitation when Accelerating - Giulietta QV

    Alfa Giulietta
    Morning all, My 2011 Giulietta QV seems to 'hesitate' under acceleration. The problem occurs in Dynamic Mode, and seems to be most noticeable between around 2500 and 3500 rpm. I'm not accelerating heavily, so I don't think it would be the traction control cutting in. I've also noticed that, if...
  8. 2004 156 JTD makes rustling noise when accelerating

    Alfa 147, 156 & GT
    When I accelerate at anything more than a crawl I get this weird rustling noise from my left front wheel area that is directly related to how fast I am going. I want to call it a "woosh" but it isn't the same as the noise the car made when the intercooler tube was cracked. It doesn't happen when...

  11. 147 selespeed jerks when accelerating from stand still...

    Alfa 147, 156 & GT
    Hi all, I love my Alfa 147 which I bought about six months ago. Had no problems with it so far however in the last month it has started to do a 'jerk' movement mainly from first gear when accelerating from a stand still. The revs struggle and seem to jump from 1000 to 2500 whilst only just...
  12. Vibration when accelerating

    Alfa 164 & 166
    Please help. When I accelerating on 5 or 6 gear and speed is about 100-140km/h appears strong vibration in whole car, not in steering wheel. When I release accelerator vibrating disappears. What I have to check? Thanks.

  14. High pitch whistling noise when accelerating

    Alfa 159, Brera & 946 Spider
    Ive noticed these last 3/4 weeks, particularly when in 4th gear or higher that there appears to be a high pitch whistling noise coming from the engine. I have a 1.9jtdm 159 SW. The pitch increases the harder i accelerate. The moment i release the accelerator, the noise stops. Very noticeable in...
  15. intermittent loss of power at high revs when accelerating

    Alfa GTV & 916 Spider
    Hi All, I've posted this before, but thought that the cause might be the fact that I ran out of petrol when I bought the car, and coasted into a petrol station..... and one of the suggestions was to try an injection cleaner in case 'crud' had got into the injectors. Well, I bought some costly...

    I have a slight clunking noise when accelerating briskly that seems to be coming from the right front wheel . . Just had a cambelt service, Q2 installed a year ago, 40000K service, the noise got louder when I had the brakes disassembled and cleaned, I am replacing all four discs and pads...
  17. 147 (SS) vibrates/jerks when accelerating

    Alfa 147, 156 & GT
    I have a 2003 147 2.0 (SS) and recently i've noticed that when accelerating (mainly from a slow speed) the car jerks (as if it is struggling to do so) and then it accelerates properly. The temperature gauge shows 90C and there is no warning light coming on. Car has done around 107000Km overall...

    Alfa 147, 156 & GT
    Hi all got a problem ( yet again ) with acceleration on my 2.4. On accelerating it is very uneven ( if it were petrol then i would suggest a blocked fuel line ) the little red light is showing when the problem occurs and only seems to clear when my foot is pressed hard to the floor ( and i mean...
  19. advice on power loss when accelerating 156 jtd

    Alfa 147, 156 & GT
    I have recently bought a 2002 156 jtd turismo, it has started to tell me to go to the dealer as it cuts the power quite often when accelerating hard but then recovers and repeats. I have been told by a dealer it needs new glow plugs but i never had a problem starting and running although the...
