Does your Cayenne not feel smooth anymore? Porsche Cayenne S Rough Idle Stumble can be caused by a number of things, today we talk about ignition misfire diagnosis.
Modern engine electronic control units are more complex than ever. Not only do they have the task of running and managing the vehicles main source of propulsion, they also have to be able to identify problems that may be occurring with the motor. This customer had a concern that the car was running rough and stumbling off idle. Doing a quick scan showed no faults, or anything that indicated an issue in the system.
When dealing with a no fault diagnostic condition, you need to go back to basics of an internal combustion engine, fuel, spark, compression and flow. The vehicle is obviously running well enough to be driven without setting a fault, so were looking for something that is still working, but not as well as it should.
Testing the various components of this engine can be time consuming and expensive if the customer is paying for each step. We first performed a smoke test of the intake systembut no leaks were present.
After watching the Cylinder smooth run deviation values, it was clear that bank 2 was running ever so slightly rougher than bank 1. Our vast experience with German vehicles has taught us that we need to see how this vehicle is actually running. On the Cayenne, bank 1 cylinders have an additional amount that greatly increases the amount of time to access the spark plugs. In order to save the customer substantially, we decided to check only bank 2 spark plugs for now.
White plugs indicate a lean fuel mixture, heat, or contamination from a non-combustible substance. Black plugs indicate a rich fuel mixture, or oil contamination. Clean light brown colored plugs indicate a proper combustion event. Extremely clean plugs indicate no spark or the cylinder being washed out by moisture vapor. There are other things to check for when reading plugs but for the sake of space these are the ones that pertain to this issue.
We have replaced ignition coils in the past for misfires, so it is in the realm of possibility that this particular bank of coils is just faulty enough to not trip the fault code. So while the plugs were out we swapped in good coils for the sake of testing, and the misfire, stumble, rough run issue was no longer present. Luckily for this Cayenne S, ignition coils was all it took to get this vehicle running smooth again.
My Porsche Cayenne s is not driving smoothly. When I slow down, there is delay in taking off. The car seem to be heavy, with loud cracking noise coming from the front drive wheel.
This cracking noise is just for few second while try to take off after slowing down say behind another car. The ride also seem to be rough and stumbling. You don,t feel that smoothness. The drive is better when on top speed, like on a highway. I would suggest that this issue is not engine related but driveline related.
Please have your driveline mounts, axles and driveshafts checked. I need your professional input on the issue of my Porsche Cayennethe engine always idles rough on start in the morning worse when weather is cold but runs seem normally when engine gets warmed up already.
I saw one suggestion in your blog, to change the coil packs and it solved the issue. I wonder if this same approach would help my car rough idling issue. Thank you so much, I would really appreciate your input on this.
Thank you so much. That vehicle is direct injection. I would have a qualified shop check the fuel system first before I replaced coil packs.

All rights reserved.An easy project for the first timer is to clean out the throttle body on your Porsche Cayenne. As the miles build up on your car, the emissions control devices on your engine allow a certain amount of air back into the intake.
This air is typically mixed with a combination of carbon and also oil vapors. Over time, this mist leaves deposits on the throttle body which if not cleaned periodically, can lead to uneven running or even a sticking throttle. Removing the throttle body is a simple procedure that can be done in under an hour. Begin by opening the hood and removing the engine covers see our article on engine compartment cover removal for more information. You'll also need to remove the front cover on the engine itself.
This is the one that reads either "Turbo" or "4. Simply pull up on it to remove. Begin removal of the throttle body by first loosening the two hose clamps holding the plastic boots to the intake plenum green arrows. You'll also want to remove the electrical connection to the throttle body in order to access the mounting pin below yellow arrow.
Squeeze the two tabs on the top and bottom of the connector and pull the switch off. Large Image Extra-Large Image. Now you'll need to remove the plastic boots from both sides of the intake plenum. Pull each boot back far enough to free it but take care not to damage the boot. The intake plenum is held to the throttle body by two long plastic T30 Torx pins.
You'll need to rotate each pin so that the mark on the pin green arrow lines up with the mark on the bracket yellow arrow. This mark corresponds with a locking tab on the bottom of the pin.
Once lined up, pull the pins up and out. This may take a bit of effort and it's not uncommon to see the locking tabs broken. If the tabs are broken, don't worry about it. Now carefully pull the plenum off the throttle body.
You'll now want to carefully lift the plenum up high enough to disconnect the vacuum fitting below green arrow.All Search Everything.

I was under constant shock! I knew it was virtually impossible, but we were going to make it! Under full pressure, the production hall was completed and the production started. That is how the wolf began its string of successes and continues to do so. In less then 5 years, REMUS managed a dynamic leap to become world leader in the manufacturing of sport exhausts In 5 different expansion stages, the production area was increased over the years and in spring reached a massive In the new Research and Development centre was opened, this opened up many different avenues in the development of mechanical and acoustic features for sport exhaust systems.
In a new hall was build with approximately 5. From an idea, an ambitious plan and only 5 employees, REMUS become over the years a renowned international business and is today a major global partner in the development and manufacturing of many types of exhaust systems.
REMUS manufactures using the latest state of the art machinery to ensure top quality for a global market Modern machinery, such as laser cutting, Hydro forming and CNC controlled pipe bending machines combined with special processing techniques guarantee products with exceptional forms and perfect fitment.

This prevents reflections, echo and hall effects and ensures -conclusive, repeatable measurements.The cold air intake was designed specifically for the Porsche Cayenne to increase horsepower and torque through the entire RPM range.
We manufacture our own intakes in Denver, Colorado. Our objective was two-fold — reduce induction resistance and minimize heat transfer to the intake cavity. The couplers are made from multi-layer, high-temperature silicone and are provided with stainless steel clamps.
With the cold air intake system one of our objectives was to create more power without losing the factory appearance under the hood. Fortunately, the end result looks nearly identical to the clean factory setup; all of the factory trim pieces are completely reinstalled and the aftermarket intake is only barely visible.
There are several more expensive brands that do not allow the reinstallation of the trim. The installation is straightforward and can be completed in approx. We provide complete step by step instructions. You can expect to see power gains of approx. Cayenne models equipped with factory air suspension route the air suspension line into the factory air box; this factory air box is eliminated with our CAI kit.
