Hi Chris, I have a audi a4 2. The problem that I am experiencing is engine surging. The surging is bad when the engine is cold and not at optimum running temperature. The rpm fluctuates up and down and I do feel vibrations as it does that. When warm it's not as bad but it still does it whenever I'm driving and the surging only happens when I'm driving. It feels like the car is being held back and I have no codes or stored codes on the vehicle.

Could you possibly shed some light on what it might be? Would the throttle position driving ensure cause something like that which is the pedal sensor and not throw a code? I have cleaned the MAF with no luck and it looked pretty new when I pulled it out but cleaned it anyway. Throttle body is new as well. Hi there. Remove the vacuum line to the valve and see if the engine runs smooth.

If the engine runs smooth, then the IAC needs to be replaced. If the IAC is working properly, then the throttle pedal position sensor is not calibrated properly and needs either calibrated or replaced. To calibrate the throttle pedal position sensor, turn on the key with the engine off and push the gas pedal to the floor slowly. Hold the pedal on the floor and turn off the key. Then while holding the gas pedal on the floor, turn on the key and release the gas pedal slowly to the rest position.

Then turn off the key. Now the throttle pedal position sensor is calibrated to the correct counts that it should have.

It normally idles around or rpms, but lately it will slow down to orthen burst up to and repeat the process again.

Rattling, Thumping

It doesn't do this all the time, maybe only half-time. Occasionally the rpms get so low that the engine dies, but that only seems to happen when I'm turning AND braking at the same time. I don't have any idea what's causing it, and I really haven't even pinned down a common variable for when it happens. It seems to have started with the cold weather, but even then I couldn't tell you for sure. It might be the intermittent failure of an idle speed solenoid. They go by a bazillion different names and have just as many variations.

For example:. It may also be, as noted in your comments, an air leak somewhere. Seeing as how it works fine above a certain RPM, I'd be willing to bet it's an idle speed solenoid of some type. Typically air leaks result in poor mileage.

Check for vacuum hoses that are torn, disconnected, or missing. You brake system relies on vacuum and an idle speed that is affected by holding the brakes probably has a weak vacuum. You can get a cheap gauge at an auto part place that will quickly tell you if you are in spec.

Last time I got it read it was for gas cap and EGR valve. Had the same problem with our heavy motorhome. Found the problem was the old fuel pump had lost pressure. Worked fine a low speeds, but would fluctuate when you gave it pedal. The shimmy? Is it 'full-time-4WD'? That may induce the shimmy by the front wheels.

Especially for social media, where content is posted and shared on a minute-by-minute basis, it is even easier to adapt your approach to your customers and professional associations.

Social media is a potentially great tool, should be used to help build and expand your business, and can be implemented without breaking the bank. That said, it is impossible to overlook the benefits of building a social media strategy, engaging with customers, and expanding the reach of your business in an increasingly digital environment. Approaching social media from a business perspective, setting up a plan, and selecting the right strategy for your business can set your business up for an effective social media campaign.

A great thing, especially for Millennials and other entrepreneurs focused on the bottom line, is that the vast majority of social media tools are free to use. Another wrinkle that can complicate your efforts to get the most for your social media dollars is that many small businesses do not put together a social media strategy that works for business.

These suggestions and ideas are certainly not meant to be exhaustive, but should give an idea of how to get the most out of social for your business, and to do so in a way that is also friendly to your bottom line. Social media encompasses a variety of options, not all of which are going to be equally as helpful for your business. There is a lot of information out there dissecting what types of demographics are on which types of platforms, but generally speaking, if your business has a Facebook and Twitter presence you are in good shape.

Few things are more depressing for consumers and customers than to look for a business on social media, to see that they do have a social media presence, but that the platforms have not been updated.

Virtually every professional group has an organizational association, but even for entrepreneurs and small business owners there are people and organizations you should definitely engage with on social media. There is no shame in observing what your competition is doing, making it your own, and customizing it for your business.

Taking the approach to social media like everything else your business does might seem a bit odd at first, but it actually makes perfect sense. Social media can, unfortunately, turn into an activity that can drain productivity and energy from your business if you let it.
