Hi I drive a 62 plate Vauxhall Astra turbo 1.4 petrol, recently the engine light has came on and is displaying the code in the title, when I get around 2500revs the car has a very slight pull back but still continues fine. I have good spark plugs, I have changed my MAF sensor and also have replaced the purge valve as this is common with my model and make, however it is still doing the same thing, wondering if anyone knows the next steps in helping me out please
