Multiple misfire codes tend to indicate a problem with the coil packs - it's a fairly common problem with the A4, moreso on the 1.8T than the 2.8 V6, but failing coil packs are never a surprise on an A4.

    Heheh, yeah the German cars are different, but I really like them a lot (I had a Nissan 300ZX before my A4). The biggest benefit to them is that they seem to be designed with servicing in mind - most things come apart relatively logically and easily. I'll check your other post and see what I can do for you there.

Vehicle looses power because EPC light stays on. plugged in diagnostic tool and it gave me multiple fault codes.


If you have "multiple fault codes", then it is likely you have multiple problems. However, without any of those codes, it would be pure guesswork for us to suggest anything.

If it were my car, I would google each code and see what the cause is, and replace what has gone bad. 220k km isn't all that much anymore.

Why the loss of power and po300 code?

http://www.obd-codes.com/p0102 Code P0300 Causes and Fixes Code p0300 is a code that is generated when your engine has a misfire that is not related to only one cylinder. Sometimes this code will be set in addition to other codes such as p0301 which means that there is a misfire on cylinder 1 (cylinder 1 is the number one cylinder when looking at the firing order. It is generally the forward most cylinder on the engine.). If these engine codes are present as well the you should diagnose those first as they are probably causing code p0300.
This code will set your check engine light and needs to be fixed as soon as possible. If it is not then you will probably need to replace your catalytic converter as well as the problem that is causing your misfire.
There are many causes for this obd code. Since it is a "random misfire" or "multiple misfire" this means that the misfire is on different cylinders and not just one all the time.
Common Causes
  • Low Fuel Pressure
  • Vacuum Leak
  • EGR system malfunction
  • Internal Engine Problems (such as low compression)
Less Common Causes
  • Faulty Coil
  • Faulty Spark Plugs and/or Wires
  • Camshaft or Crankshaft sensors
  • Ignition module
  • Computer

DTC P0300 indicates random multiple misfires were detected. You have replaced a lot of parts but probable causes include:
1. Fuel contamination (not mentioned above)
2. Ignition module (included above?)
3. Fuel system

Multiple misfire on 2004 gmc Yukon 4.8 liter engine, can't diagnose?


Hi kathy
I am sure that your YUKON engine is not idling smooth.
the problem seems to me like you have a vacuum leak, better check inlet manifold and the vacuum hoses.
good luck

2000 Buick LeSabre Will not start Replaced cam


Multiple engine misfire is related to the coils and the ignition control module. I have a 2002 with the 3.8 engine. It has three coils. I just went through this problem. I bought one coil and tried it in each position with no improvement. It was the ignition control module. Mine is located under the three coils. A relatively easy item to replace. Cost about $140.
