Why is there no warning light on my Boxster?
If you’re able to use a Porsche-specific reader (PIWIS or equivalent) it should be able to home into the problem more accurately. Most probably the problem is lambda sensor related, but there are sensors on both banks and I’m not sure that your reader will be able to distinguish between them whereas a Porsche-specific reader can.
How to know if the Check Engine Light is an emission?
Unfortunately it often takes several trips out with the car before the light shuts itself off so it might take awhile before you know if the problem has been solved. Check the dipstick in the oil compartment of your engine to make sure it is inserted properly in the tube. If the dipstick is not in tight it may cause the car to idle funny.
What should I do if my check engine light says misfire?
If your “Check Engine” light diagnosis shows a generic cylinder misfire code, you should start with the most likely culprits first. Fortunately, these are also the cheapest and easiest. Spark plugs are as low as $2 each, and can be swapped in about an hour with varying difficulty.
What causes a Porsche Boxster engine to leak?
On the early cars, Porsche also used a center bolt to secure the IMS bearing that was too weak and sometimes snapped. If this bolt breaks, then the intermediate shaft begins to float around in the bottom of the engine, and you can soon experience catastrophic engine failure. This area is also highly prone to leaks.
What does a misfire code on a check engine light mean?
Misfires that turn on the check engine light and log a cylinder-specific fault code are the easiest to diagnose. The OBD II system will identify the cylinder (s) that are not contributing their normal dose of power and set a code that corresponds to the firing order. A P0303 code, for example, would tell you that the No. 3 cylinder is misfiring.
Is it possible to find a misfire in a Ford?
It’s possible to find a misfire in your Ford, even if there is no check engine light. All you need is an OBDII scanner with Mode 6 function. It is a common situation. You’re driving your F150, F250, E150 van, or Expedition, etc and you can feel the engine skipping here and there.
Why do I keep getting misfire codes on my cop?
Insufficient valve lash, a broken piston ring or a leaking cylinder head gasket can cause a partial loss of compression. Depending on where the vacuum leak is on the manifold, it can generate random or specific cylinder misfire codes. The most common failure in COP ignitions is carbon tracking or “flash over” on the spark plug insulator.
What causes a car to misfire after 50, 000 miles?
After 50,000 miles or so, OEM carbon-core ignition wires develop too much internal resistance, which weakens the spark and increases the risk of misfire. High-mileage plug wires also can develop cracks that leak current to ground or to other wires, shorting the spark before it can reach the plug.
