Why is my SEAT Ibiza losing power?
I have a 2004 SEAT Ibiza 1.2 SX which has developed a problem with acceleration.
It struggles to get up to speed, but will maintain speed once it has got there. It does pull away, but is still very sluggish. The engine also has a louder whirring whine noise. This has all happened in the last three weeks after hitting 60,000 miles.
My local garage have found no faults and it has had a service in the last nine months. They say there is nothing wring but I am very aware of a change in how it drives.Can you help?

We assume that the local garage has carried out a diagnostic check and found no faults showing.
If so then we would suggest that the following is checked.
1.Air intake system/vacuum system for leaks.
2.Fuel filter
3.APP(accelerator pedal position sensor)
4.FP (fuel pump)
5.HO2S (heated oxygen sensor/s)
6.ECT (engine coolant temp sensor)
7.MAP (manifold absolute pressure sensor)
8.KS (knock sensor)
9.Injectors
If they did carry out a diagnostic (correctly) then most of the above sensors listed above should (if they are faulty) have shown up on the diagnostic.
You may want to check with the local garage to see what checks they have done.
