Hi there,

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?


Customer: replied 1 year ago.
replaced coils spark plugs leads filter just no power
Expert:  Gary replied 1 year ago.

I would be looking at the fuel pump.

Sounds like low fuel pressure to me.

Have you had a mechanic look at it?


Expert:  Gary replied 1 year ago.

Hi again,

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.
