I have a problem but im not sure what i can do. I have an mk4 04 1.6 sxi astra and when im driving the car seems to not accelerate like it used to. Dont know really how to explain it. I have been told to check the air filter and the spark plugs to see if they are firing. I have checked the air filter and it is clean but i dont know how to check to see if the spark plugs are firing
Can someone please help me.
