• Citroen saxo 1.4i auto - Sluggish acceleration problems 8 Feb 2011 (Forum)
  It has a multi point injection system of which I have removed all the injectors and fuel rail and cleaned them all, but i'm sure if these were the problem it wouldn't run ok in idle, I have also removed the throttle body and all the accompanying sensors, and cleaned them but still to no luck. I'm lead to believe in thinking it could possibly be the Throttle potentiometer, as these can wear out??? Any thoughts from anyone would be a help...O and also I have had the ecu checked out and plugged into a gizmo, but no fault codes were shown.
• Suzuki Wagon R+ 1.2 - Vibration under load/misfire 17 Jan 2011 (Forum)
  Ive put some injection cleaner through which makes a temporary improvement ( but not a fix ), but im unsure if its the cleaning effect or the octane boost the stuff sometimes gives. Its had new plugs and leads in the last month and the EGR has been cleaned out. It does have a pattern part exhaust section which sounds a bit throaty, not sure if that would cause such an issue. My instinct was its either a fuel delivery issue or a sensor, but I may be way off and I dont know enough about modern engines to be any more specific.
• 1989 ford escort 1.6 CVH - Engine trouble 23 Nov 2010 (Forum)
  Now when I parked up I turned it off and then tried to start it again and it would not turn over fast enough to start (as if the battery had gone flat). I left it for 10 mins and went back, i noticed that one of the HT leads was loose so connected it back up and tried to start it again. This time it started no problem but now it runs very lumpy as if its sometimes running only on 3 cylinders and sounds very tappety, also the light are still dimmer than they should be.
• Zafira 2002 1.8 - Strange power loss on motorway - left curves only! 27 Oct 2010 (Forum)
  Effect is more pronounced on longer or sharper left curves. Applying a bit of logic, I thought that the petrol tank must have two supply pipes leading out of it, one on the left and one on the right, and that the right hand exit had become blocked with crud. As the petrol swills to the right side on left curves, the left pipe loses supply and the right pipe, being blocked, can't compensate, hence temporary fuel shortage on prolonged left hand curves.
• Ford Fiesta 1.25 Zetec (1997) - Fiesta 1.2 Uneven Idle problem 18 Sep 2010 (Forum)
  We have changed the temperature sensor , the plus and HT leads, and finally the Mass Airflow sensor. It is fine sometimes, but then the problem reappears.   Can anybody help, please???
• Car technical advice - Tech Section V Magazines 20 May 2010 (Forum)
  Then you find yourself reading  questions and answers and thinking I`ve paid for this... And of course here it`s free on seemingly the internets leading website on tech and car related issues. What might still draw you to a Mag then? With it`s often wrong tech advice? Pictures perhaps.. Something for forums in the future perhaps - for example who saw those pics of sludgeon the US BMW forum?
• citreon synergie 2.0 petrol and lpg - Engine running problems on lpg and petrol 21 Feb 2010 (Forum)
  When the engine has reached its normal operating temperature for this time of year (according to the temperature gauge – about 80-90 degrees Celsius) all the problems will go away on both petrol and gas and no longer stall at junctions or race. The car had a full service including spark plugs, HT leads and brand new coil pack Another piece of info which may be relevant: The yellow petrol low warning light stays on far too long before the needle moves up and over when there is enough petrol in the car – when you start the engine initially.
• Ford C-MAX (2003 - 2010) - 04 1.6 - Flashing management/battery lights 1 Dec 2009 (Forum)
  My car started juddering and had lack of power and was like a knocking sound, so my Dad took the car to a garage and he was told the HT Leads so we changed them. The noise hadn't gone completely but was quieter!.Because the noise still remained we took it back to the garage and we changed the Spark Plugs and also changed the Coil Pack. The car worked fine for aprox 3-4 week.
• Ford Probe (1994 - 1998) - 95 2.5 Electrical / water short 20 Nov 2009 (Forum)
  I noticed that the fuse box in the N/S engine bay was making a buzzing at the time of the problem, so maybe this could be a lead culprit? {shouting in header amended. Welcome to the forum, btw}
• Volkswagen Passat (2001 - 2005) - 01 2.8 Exhaust white smoke after 2 months left sta 25 Oct 2009 (Forum)
  My first post: I need to sell my beloved VW Passat 4motion but it has been SORN off road for a couple of months - I have started it every 2 or 3 weeks for a few minutes during its time on the driveway but today when I checked its battery was flat. It started immediately with jump leads but there was a fair bit of white smoke coming out of the exhaust at all revs. I thought it might clear as the engine warmed but 15 minutes later it was still there (including 5 mins at 3000 revs).
• Drivers should pay up even if they win at court 21 Oct 2009 (Forum)
  Peter Roberts CEO of the Drivers' Alliance said "it is fundamentally wrong for the state to financially penalise innocent drivers who are simply seeking justice against a faulty conviction". Jeanette Miller, of Geoffrey Miller, a leading motoring law firm has raised a petition on the Downing Street website and the Drivers' Alliance urges everyone to sign it. If the principle of innocent until proven guilty is to be upheld in this country then it is imperative people who win a court case are not financially disadvantaged for defending themselves.

• Body assembly 29 Sep 2009 (Forum)
  Went to see our American lady friend yesterday and for the first time saw her Mazda 3 (saloon not hatch) in a fetching shade of kingfisher blue. I noticed immediately that the shutline at the leading edge of the bonnet lid was too wide, and wider at one side than the other, ruining the look of the car. Suspecting poor crash damage repairs I looked uner the bonnet. Couldn't see any evidence of a serious front impact, but looking closely could see that the front panel, all plastic, which is quite complicated and has the headlights inset in it, needs to be refitted by someone who isn't a chimp.
• Volkswagen Polo III (1994 - 1999) - 95 1.0 Engine not firing up 26 Aug 2009 (Forum)
  I'm not convinced, especially after googling around, because of the symptoms, such as the engine turns and turns but won't start at all (not the "classic" firing up, then cutting out). He checked the HT leads and said there's no spark from the coil but didn't think the fault was with the coil itself as there would still be a weak spark? Well I've had a better look in daylight and taken some pictures, the coil looks knackered to me (cracked/charred plastic, light corrosion within).
• On transient human motoring time - toads lost... 30 Jun 2009 (Forum)
  Now the hills are dark at night - a larger, nearer, Moon casts shadows as golden irises move down over the hills, still following the beat - the internal tune of amphibian calling.. The Pied Piper leads, over the ancient battlefield, a road, now deep below, under 30 yards of peat . There had been a distant, distant, call...the call of natures fortune now restored.

• Vauxhall Astra H (2004 - 2009) - Dumb diesel design or cant be helped? Which? 8 Jun 2009 (Forum)
  As most modern CR diesel owners know, the EGR valve will eventually soot up one way or another, leading to the valve sticking. This requires either a jolly good cleaning of the valve or replacing it to the tune of about £125 depending on wether its salvageable (these valves can corrode internally so siezing the mechanism) Symptoms of a sricking open valvle are (among others) usually low power at low revs - feels like turbo lag.
• Ford Mondeo III (2000 - 2007) - 04 2.0tdci Won't start; flashing glow plug light 1 Jun 2009 (Forum)
  Next morning would'nt start, battery getting low, called out AA who checked fuel to rail, ok good pressure and a slight pulse to glo plug electronic leads. Tried different key still did'nt start, put on diagnostic machine faults found P0191 fuel rail pressure, P0204 injector CR, P0340 cam sensor (twice) and P8888 control pressure injector and finally P1000 manufacturers specified fault.
• Ford Fiesta (2002 - 2008) - 03 1.4 Noise From Engine 14 May 2009 (Forum)
  I then explained my problem to garage left it with them for an hour, they then rang me back and explained my coil pack had gone, my oxygen sensor had gone and also my spark plugs and leads also needed replacing. i had the work done and the sound had gone when i picked it up, but the next day it was back?!? it seems to be louder when the engine is warm, does any one have any ideas as im begining to think its something serious?
• Peugeot 307 SW (2002 - 2008) - 02 2.0 Low on power/exhaust smoke suddenly appeari 16 Apr 2009 (Forum)
  The air filter has been changed and I was going to change the fuel filter and disconnected the 3 fuel feeds and the electrical connection. Unfortunately the wrench I had was not big enough for the housing top,so I reconnected the fuel leads etc The car started and idled over without any problem so at this time I decided to use a charge and start cable (I have never used this before) to boost the battery on another car. During this time the 307 started to blow smoke from the exhaust - it has never done this before There are no fault codes and showing and I cannot see how the charge and start cable has caused this problem So I have 2 questions : 1) according to Haynes it is almost impossible to unscrew the filter top without damaging the housing.
