SOURCE: 2000 ford explorer 4.0 x-engine is stalling, missing and lose power while driving

I personally would check the fuel pressure. Then I would go back to the coil. I have seen brand new bad coils out of the box. The symptoms of a loss of power point to this component, especially if the car idles well, but loses power when accelerating. Please do not rate this reply - we all are left to grasp at straws since you have changed pretty much everything. Good Luck. Please post the final fix of the problem.

SOURCE: where is the fuse for the radio , stereo for volvo s40 xs

Passenger compartment fuses are all behind the drivers side (left) kick panel. You should only need a #2 philips head screw driver to remove 4 or 5 screws. After you remove the screws gently pull out on the lower right corner to disengage a plastic tab. The panel then should now come out disengaging metal tabs on the upper to corners. Fuses are on the left.

Well depending on if its an electronic key, or has an anti-theft module on it, you may be forced to purchase from the dealer.

On the other hand, you may just be able to go to a local locksmith and save some bucks! hope this helps!

It might but what exactly are the codes. Before you change the Mass air flow sensor, try cleaning it first with a can of mass flow cleaner.
If your running a oil K&N filter, there could be some oil residue on the sensor. Start with that and change the filter or clean it if it's a K&N.
The O2 sensor's could be bad also, you really need the code's to be sure what sensor is giving you the faulty signal.
Good luck and hope this helps.

Error code 55 on vauxhall meriva whats it mean


Error 55 is Diesel Particulate Filters (DPF)
Reducing diesel soot emissions by 80%

If you're buying a new car and plan to use it mainly for town-based, stop/start driving it would be wise to avoid a diesel car fitted with a Diesel Particulate Filter (DPF) because of the possible hassle of incomplete 'DPF regeneration'.

The exhaust emissions standards for new cars have effectively required fitment of a DPF in the exhaust of diesel cars since 2009 when the 'Euro 5' standard came into force. In fact, many cars registered before 2009 will have had one fitted too in anticipation of the change in standards.

Standards aim to deliver an 80% reduction in diesel particulate (soot) emissions but the technology's not without problems - AA patrols are regularly called to cars with the particulate filter warning light on indicating a partial blockage of the filter.

Even if your driving isn't mainly urban/stop-start, changes to driving style may be required to get maximum benefit from these systems.

How do they work?
Diesel Particulate filters (DPF) or 'traps' do just that, they catch bits of soot in the exhaust.

As with any filter (think of the bag in your vacuum cleaner) they have to be emptied regularly to maintain performance. For a DPF this process is called 'regeneration' - the collected soot is burnt off at high temperature to leave only a tiny ash residue.

Regeneration may be either passive or active.

Passive regeneration
Passive regeneration takes place automatically on motorway-type runs when the exhaust temperature is high. Because many cars don't get this sort of use car manufacturers have to design-in 'active' regeneration where the engine management computer (ECU) takes control of the process.

Active regeneration
When the soot loading in the filter reaches a set limit (about 45%) the ECU can make small adjustments to the fuel injection timing to increase the exhaust temperature and initiate regeneration. If the journey is a bit stop/start the regeneration may not complete and the warning light will come on to show that the filter is partially blocked.

It should be possible to start a complete regeneration and clear the warning light by driving for 10 minutes or so at speeds greater than 40mph.

If you ignore the warning light and keep driving in a relatively slow, stop/start pattern soot loading will continue to build up until around 75% when you can expect to see other dashboard warning lights come on too. At this point driving at speed alone will not be enough and you will have to take the car to a dealer for regeneration.

Expensive repairs
If you continue to ignore warnings and soot loading keeps increasing then the most likely outcome will be that you will have to get a new DPF costing around £1000.

DPF additives
The most commonly fitted type of DPF has an integrated oxidising catalytic converter and is located very close to the engine where exhaust gases will still be hot. This heat means that passive regeneration is possible.

There's not always space close to the engine though so some manufacturers use a different type of DPF which uses a fuel additive to lower the ignition temperature of the soot particles so that the DPF can be located further from the engine.

The additive is stored in a separate tank and is automatically mixed with the fuel whenever you fill up. Only very small quantities are used though so a litre of additive should treat around 2800 litres of fuel - enough to cover 25,000 miles at 40mpg.

You will have to pay to get the additive tank refilled at some time in the car's life, and we've heard reports of dealers charging up to £200 to re-fill a half empty tank.

AA experience
We're seeing some evidence of DPF systems failing to regenerate even on cars used mainly on motorways.

On cars with a very high sixth gear the engine revs may be too low to generate sufficient exhaust temperature for regeneration. Occasional harder driving in lower gears should be sufficient to burn off the soot in such cases.

With this type of DPF regeneration will be initiated by the ECU every 300 miles or so depending on vehicle use and will take 5 to 10 minutes to complete. You shouldn't notice anything other than perhaps a puff of white smoke from the exhaust when the process is completed.

There's no evidence in AA breakdown data that the problem's going away - newer car models seem just as likely to sufffer DPF problems if not driven 'correctly' as those built when DPF's were introduced.

Check the handbook
If you buy a car with a DPF fitted it's important to read the relevant section of the vehicle handbook so that you understand exactly what actions to take if the warning light illuminates and how, if at all, your driving style may need to be adjusted to ensure maximum DPF efficiency and life.

P0471 and p2002 codes, Audi A6 2.0 DPF S-Line Auto


The DPF is designed to be self-cleaning to a certain extent if the engine is run for a good length of time the deposits should burn off. I would kick up a fuss with Audi about the warranty, ask them to show its exclusion. Unless the DPF has become physically damaged by something you have done then they need to have it fixed as it is a result of the deficiency in their design. This is not like some damaged tyre, open to abuse by the driver, the DPF is integral to the vehicle operation and through no commission on your part it is not functioning as it should.

DPF FULL


The DPF is designed to 'Burn off' the soot deposits that accumulate, but in order for this to happen the exhaust has to become really hot. The DPF will fill up if the vehicle does a lot of short trips and the exhaust fails to get hot. The cure is a long hard drive

1995 volvo acts like its not getting fuel properly its an 850 wagon with the biggest motor put out that year 5 cylinder


It sounds like it's either your fuel filter or your fuel injecters. If you change out your fuel filter don't forget to release the pressure in the fuel line before you take off the old filter. The pressure may be strong enough to knock the filter from your hands, & the spraying gas could harm you too. As for the fuel injectors the best stuff I found is Lucas brand injector cleaner. It's $5.99 at Auto Zone. pour a bottle in a full tank & take a 15min drive down the highway. You may see a light smoke coming from your tail pipe but that's what you want. It's the sludge & gung you don't want coming out.
