Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
How old are your spark plugs and fuel filter?
You could have one of many reasons for low power.
Does it feel like running out of fuel, or running on 4 cylinders etc?
I would be looking at the fuel pump.
Sounds like low fuel pressure to me.
Have you had a mechanic look at it?
Just checking in to see how you have gone with your problem.
Your description of low power but no misfiire indicates typical low fuel pressure .
I hope this helps.
