• Cigarettes chucked out of cars 7 Apr 2003 (Forum)
  I know it might seem silly, but I always wonder (and am alarmed by) the thought of what could happen if it gets lodged somewhere in or under the car close to a fuel line. Especially at night you can see the amount of sparks etc. that come off - makes you think! Y
• Exhaust emissions failed 28 Mar 2003 (Forum)
  The joint at the back box has the slightest of leaks, and the tester has told me that it may be drawing in air from this point and causing the problem, but what I don\'t understand is where the CO is coming from. He also advised me to put in some fuel cleaner to clean the single point injecter, combustion chambers and lambda sensor. Is this likley to work? Reggie
• lack of power in citroen bx diesel 30 Dec 2002 (Forum)
  I've just changed the air and oil filter and the oil, and it's just had a new cam belt, but the problem still exists before and after these changes. Fuel consumption is fine, there's no loss of oil and it starts ok. Any ideas of what the problem is?
• What`s happened to Two Stroke Developmen 4 Nov 2002 (Forum)
  I know the barrier in the past was possibly horrendous exhaust emissions, but I would have thought that with modern fuel injection systems & computerised engine management, these problems could be resolved!! I believe I read that Ford were running an experimental engine in a Fiesta, but don`t know what came of this. Any info would be appreciated
• water vapour injection sysytems 16 Sep 2002 (Forum)
  Its because the air drawn into the intake is denser with the water particles in it (I think). I've checked the fuel consumption on my car(old model Mondeo diesel)on days like this, and it is slightly better than on 'normal' days. I'm sure I heard of a system for injecting water into the inlet manifold many years ago.
• Golf MK IV 1.6 8V erratic idling 5 Sep 2002 (Forum)
  It's got worse lately but has always done this to some degree. Seems to be OK when the engine is not fully warmed up. No problems with fuel economy or when on the go. Does anyone know what the most likely problem is or which areas should be looked at first?
• petrol bias 26 Apr 2002 (Forum)
  The first a feeling that your growing biased to the manufacturers regularly and increasingly giving them the benefit of the doubt. And secondly regularly endorsing often the more expensive branded fuels offered by esso and shell etc. especially for high performance or sporty models. I know of two police forces that fill all there vehicles including patrol cars and high pursuit vehicles at the local supermarket, strange given what you say about performance and damage?
• Rover 416 / yr. 1994 10 Apr 2002 (Forum)
  There appears to be no problems at all when under acceleration and the car is generally performing well. Programmed fuel injection is fitted with,(so I am told) little scope for adjustment.
• Tyre Test Results 18 Dec 2001 (Forum)
  The cost of tyres is now the third highest element of car ownership, after depreciation and fuel. This is because service intervals have increased and wearing parts last much longer, while tyres wear out quicker because of "better" rubber compounds, tread patterns and suspension design. What we need is published comparative data for tyre road tests so that we can choose which tyres for our cars.
• Non-ECU Diesels 5 Oct 2001 (Forum)
  Cavalier Replacement? thread, David Woollard made the point: ?It is still a point everyone has to learn that ECU fuel injection in old cheap cars is going to be a major problem in years to come, often they aren't worth fixing.? He went on to suggest a (non-ECU) Xantia diesel. This is a point that is regularly made, for the benefit of those of us that don?
• Rover 820 injector question 17 Sep 2001 (Forum)
  at a cost of £800, obviously out of the question to him. It's a 91 model with "only" 80k and he'd like to keep it, so could any kind soul recommend a fuel injection independent in the Heathrow area or other tips to get the car back within limits? Cheers Colin
• Wide body Alfa 155 20 Aug 2001 (Forum)
  I understand the post 95 cars should only be considered and am thinking the 2L 16v (150bhp) that combines power with reasonable fuel ecconomy is my best bet. What spec does the sports option add? I am aware of the Professor Brainstorm designed electrics, and the usual service history points to look out for, but anyone out there with any particular knowledge of this series and any handy hints............Thanks and all that
• Re 'Chipping' 27 Jul 2001 (Forum)
  A friend has recently had his BMW 3 series re-chipped and not only has it increased his performance but he says it has improved his fuel consumption. Apparently it has not affected his warranty. I have a Honda Accord 2.0I SE VTEC and wodered if it would be an advantage to look into re-chipping and whether it is likely to give me the same benefits without affecting warranty.
• 4 Wheel drive (cars) 30 Apr 2001 (Forum)
  of 4 wheel drive as fitted to road cars (not off-roaders). Typically Quattro with Audis. Presumably there is a loss of accelaration and fuel efficiency? ...more drag, two gearboxes. Also given typical UK weather is rarely extreme, and roads are fairly good, are there really and benefits if you're using the car as your everyday transport?
• Holley Carburettor 30 Mar 2001 (Forum)
  I would appreciate advice on: A)recommended products/methods to clean out old petrol from a Holley carb (car has been left standing for some time and old fuel will have evaporated by now leaving a non-combustible residue behind) B) Any suggested Holley experts in the Surrey to get the carb set up? Jet sizes. etc. It was always a devil to start before and time won't have helped it!
• Grade of Petrol 20 Nov 2000 (Forum)
  I've got a 2.0 Focus ESP and am slightly disappointed with the fuel consumption - I get 28 mpg on my daily commute, 32 mpg on a long run. I do have a heavy right foot though! I was wondering if I switched to 97 octane from the 95 I cuurently use if I would get better mpg and performance..

  I'm after a cheap and reliable car to run pop-ups from - what do you suggest? 6 Dec 2024 (Ask HJ)
  My Suzuki SX4 S-Cross has been deemed a write-off sadly. I enjoyed it for the height, looks, modern feel, boot space and easy flip over seats as I carry...

  What do I look for when buying my first car? 21 Jul 2023 (Ask HJ)
  I am finally looking to buy my first car (having been driving my mothers for about 10ish months). I am particularly interested in the Peugeot 107 (or Citroen...
• Renault Clio - Should I change my car to a diesel? (advice) 3 Jun 2022 (Forum)
  However, very recently I have done a lot of travelling far and wide over the UK and in the last 3 months I have totalled up my fuel bills and this has come to way over £500 – nearly £600!. I know were in situation where fuel prices are rising weekly (sometimes daily where I live). I have many more trips planned ahead which will be long distance, so this makes me conscious of the fact the price of the petrol I will be consuming will be an expensive outgoing.

  Is there such a thing as an economical hot hatch? 17 Oct 2018 (Ask HJ)
  I like the idea of have a warm/hot hatch for my next car but after driving a car does 40mpg in most town driving I am worried about the mpg being too low...
