Hello Guys!

Need some real help here.
I have a 1.4 Ibiza petrol, 60 Plate, and 58,000 miles on the clock.

A few months ago it developed a misfire, changed spark plugs, and All the coils with then best ones available it was sorted.

Over the last few weeks I have noticed a strange vibration noise past 4000revs if I accelerate hard, wasn't too worried and put it down to a loose fitting somewhere or something.

Now in the last few days the car will rev to 3000 when stationary but when it hits 3000 it will judder up and down and the rev counter jumps. If you drive it in gear it will rev past 3000 fine, vibration noise at 3500 and seriously starts to judder. Will not rev anywhere near what it normally will.

It's been getting worse recently. I was driving to an emergency dentist today down the motorway at about 60mph, There was a real noticeable lack of power when you put your foot down. So the car then starts to gently misfire/Judder. I slow down, judder continues. At this point I can even keep to 40 and pull over to the hard shoulder. Turn the engine off for a few minutes and then manage to make it back home around 60.

I have no check engine light or any other warning light which is baffling me :blink:
It also seems to be slightly louder when pressing on the gas like a loose exhaust type sound.

Anyone got any ideas? I'm pretty good at doing jobs myself but I have no idea where to start.

Cheers Guys

Sean

Even if it doesn't throw a CEL it could've stored fault codes. Can you get it on VCDS to check?
How's it on idle?
Loose pipework, bad O2 sensor, fuel pressure regulator, dirty or bad MAP or MAF (I don't know what you have)?
Get it on a code reader, that will lead you to the right direction.

It idles perfectly fine, nothing wrong at all! As soon as you rev it up to 3000 thats when the problems start.

Yeah going to take it into and see weather anything shows up.

Cheers

I'm guessing that you do know that it will not rev much above 3000 RPM when the car is stationary? That is not a fault, though something is wrong while you are driving it.
