My C5 2.0 Petrol (2002) Estate Lost Most Of It's Power

[Josi52d]

I was driving on the motor on my way home after work, 8 miles into the journey while cruising at 55 mph the engine lost power down to below 2000 rpm and forced my to coast into the nearest off ramp and stop the car. The RAC came and engine diagnostics and codes suggest failed Ignition Pack. Was towed home, ordered and fitted the new Ignition Pack with the same result: hard start, low revs and eventually cutting out. 

 

I love my car and intend to keep it. It's in very good mechanical condition otherwise. Please can somebody suggest to me what could be the cause or causes. It certainly wasn't the I.P.

 

Any suggestions, much appreciated.

When changing the ignition pack it is also good advice to replace the spark plugs in case they are the cause of the fault. You also need to check all the wiring for damage/bad connections.

 

Can you put the fault codes on here. Which engine does your car have, if the hpi petrol the fault codes are sometimes different to standard definitions.
