Reasons Behind Acceleration Stumble in MINIby fastladmin November 17, 2018
MINI cars have grown to be one of the most highly desired vehicle son the market today. They’re a combination of economy, luxury, and power – the three things that every automotive enthusiast (even the average driver) could wish for. That’s the great news; the bad news is that these cars encounter performance issues just like every other car out there. Fortunately, if you’re reading this article, then you’ll wind up being a little more informed on how you can prevent these performance issues in your own vehicle.
Acceleration stumbling is one of the more notable MINI performance issues that has been well documented over the years. MINI vehicles run into this problem for a number of reasons, and the cure isn’t always simple. Therefore, the first and most important thing you should do is find an automotive shop near you that specializes in MINI servicing and repair. It’s a good idea to spend some time informing yourself on how to address and/or prevent acceleration stumbling in your MINI vehicle, so off we go.
What Does Acceleration Stumbling Mean?
If you’re not sure if you’ve experienced acceleration stumbling or not, then it’s likely that you haven’t – the experience can be jarring and surprising to say the least – especially if you know how well your MINI can perform. Acceleration stumbling feels like a jerking or bucking motion, which causes drivers great concern usually. If you experience this symptom in your own MINI (or any vehicle for that matter) it is essential that you bring the car in for diagnosis and treatment right away; the longer the issue goes on, the more extensive the repairs may be. If acceleration stumbling isn’t remedied, then you might begin to experience other more serious symptoms like engine misfiring or engine failure, depending on the source of the initial problem.
Symptoms that Coincide with a Loss of Power
There are usually other symptoms that occur alongside acceleration stumbling, so it’s important to remain vigilant and have your car inspected routinely. Furthermore, if you notice any of the following symptoms in your own MINI, it is essential to have the problem addressed by a MINI specialist right away:
• Check-engine light comes on
• Failed smog tests
• Lowered fuel efficiency
• Engine misfiring
• Visibly dirty fuel filter
• A whining engine sound
• Moisture on the distributor cap
• Visibly worn or damaged spark plugs
What Are the Possible Causes of Acceleration Stumbling?
Since there are several different potential reasons for your MINI to begin stumbling upon acceleration, your MINI specialist will need to perform a differential diagnosis to rule-out extraneous causes. However, there are a few more common sources of this symptom in MINI vehicles in particular:
Failed or clogged fuel injectors
Your car’s fuel injectors perform the important task of spraying quality fuel into the engine for the appropriate fuel/air mixture for combustion. If the appropriate mixture isn’t established in the combustion chamber, it can certainly lead to jerking, bucking, or acceleration stumbling.
A failing or damaged throttle position sensor (TPS)
This component in your MINI is a complex part that helps to determine what the proper fuel to air mixture should be at any given point, depending on the driving conditions and the demands placed on the car by the driver. If you put your foot down on the gas pedal and the TPS isn’t working properly, it won’t know what the proper ratio of fuel to air should be to optimize performance, therefore leading to acceleration stumbling.
