Hi All,
I have a 04 Vauxhall Astra convertible that is giving me a right nightmare.
When the car is idling it's fine, accelerating fine but when at a crusing speed the car seems like its missing!
I've had the EGR valve changed, MAF sensor changed, coil pack changed, new plugs, throttle body cleaned. All parts are new and genuine vauxhall.

Do you know of anything I may be missing

Could be an injector, coil or internal engine.

Start with a compression test to verify motor is good.

Injectors need to be checked, vacuum leaks, many other possibilities.

What were the compression results.

Lambda Sensor Universal.

Bought one today for the car. Has 2 white, black and grey wires.

Which wires to I connect these to on the harness?

Cheers

Hi, I have exactly the same problem. Was it the Lambda sensor?
