my vw polo 1.4 2009 blm enjinmisfiring, backfire, hard start, petrol smell, no power when accelerate, and what can i use to remove stubborn spark plug, libricant, please advice

[EX-DOHCTOR]

Spray some penetrating lubricant like Q10 onto the threads, gently tap the metal base of the spark plug with a spanner at the same time.

Be vary careful when removing a tight plug, last thing you want to do it strip the thread in the head.

Have you checked that there is spark coming from each plug lead?
