Hi All

My wife has a 2005 1.5L Getz. Starts and idles fine and pulls fine. When the revs start to get higher it has a slight hesitation and you can feel the engine shuddering a little. I have just thrown new plugs in so it's not that. It's not contaminated fuel either as it did it with the old tank of fuel and she has just filled up and still doing it. I'm thinking basics like fuel or air filter. What else should I be looking at?

Thanks

Ignition coils and HT leads.

Look under the bonnet at night when it's dark. Run the engine at idle and repeatedly snap the throttle open by rotating the throttle cable pulley by hand.
Watch around the coils and leads for little sparks jumping to the engine block.

Did that before I changed the plugs. No freaky light show

Check the leads with a multimeter. Resistance should also show if the wire is bad or not. But to me, high rpm suggest fuel problem.
