Bought a used 2002 Corsa Rogue this year, May 2010, at 134000kms.
Worked fine, no problems for about 4 months, then the headaches started.
At first, it started coughing (jerking like there was no petrol) while doing about 110km/h. This was the first warning sign. Took it in, had the fuel filter replaced (even though this was before service time). It worked well for a week, then started coughing and needed to change down to recover. This issue got more and more frequent, and then it started losing power (while driving at any speed, you would hear the revs high, but the rev counter would gradually go all the way down to zero, till the car switched off).
Had to to wait 10-30 minutes, started the car, and away it went with no problems - sometimes. At other times, it would go 300m and then it would cut out. Took it in for diagnosis and checkup, no problems found. Another mechanic who had one suggested we replace the fuel relay. This was done, car ran with no problems for 3 to 3.5 weeks, and then all of a sudden started coughing again, and losing power again. Took it to an ex Opel mechanic, and he stated the possibilities of the cause of the problem I am experiencing:
Fuel relay - This was changed - R470.00.
Idle control valve - R3200.
Mass airflow sensor - R1900.
Crank position sensor - R2800
Coil pack - R4000.
As I do not have the money to replace all of these items, I drive on the extreme left every day, waiting for the coughing, then change down and hope it kicks in again.
The coughing and losing power is like it's not getting fuel. This happens even with a full tank. It can occur just after starting up in the morning, or after 5 minutes driving, or after a day of driving.
Any Opel - car never again!!!
