2008 bmw 328i mass air flow sensor problems

This doesn’t mean that I scratch it off entirely as a possibility, but I do put it on the backburner. If I’ve replaced something well within the lifetime of the part I know it’s probably not that part. The log also comes in handy when I am diagnosing a problem such as a rough idle. It helps me gauge for myself the quality of certain parts that I buy online or from autoparts stores.

This helps me stay organized and reminds me when the last time I performed important services.

I typically keep a log in my car with dates on all the repairs I have made on it. So how on earth does a DIYer like you and me narrow the list down? Diagnosing The problem in diagnosing a rough idle is that there are just so many possibilities. Whew! That’s a lot of possibilities isn’t it? There’s more than ten things on this list, and trust me there are other potential candidates as well. Just to give you a quick list of possible problems: There are some idling problems that are vehicle specific issues, but for the most part a bad idle can be caused by any of these parts in any car. A slip-up from a spark plug, a fouled fuel filter or even a tiny crack in a vacuum line can cause your car to run like crap. There are a number of components that have to work correctly for your vehicle to idle smoothly. Unfortunately our cars are quite demanding. Anyone of these components has a problem and the vehicle will idle rough or not at all.

Our vehicles are sensitive, they need the right combination of spark, fuel and air to idle smoothly. When somebody says that there vehicle is “idling rough” this usually means that the revolutions per minute (rpm) gauge on your instrument cluster is rising and falling or maybe the car idles really low at first and then smooths out after a few seconds. At its worst a rough idle in a vehicle may cause it to immediately cut off and can be a sign of a bigger issue. In this article I will discuss the various causes of a bad idle, what you can do to diagnose it, and how to fix it. When certain parts go out on a vehicle they can cause an annoying rough idle.Īt its best a rough idle can seam harmless and may be ignored as simply a quirk of the vehicle. One problem that is pretty universal is a rough or bad idle. Although cars have varied greatly over the years in size, construction, and complexity, there are some attributes and issues that are common to pretty much any car ever made.
