Not sure but when I take off fast, or put my foot down, my BA just shudders a little bit, you hear the engine struggle try to do it. You can ease into fast speeds, but when going from a green light into an 100 zone and I try take off fast to get my awesome ford power.. It just does this. Any suggestions?

Coils.

A lot of people are saying this, how would I go about getting new ones?

Genuine ones would be my prefered choice so try your local Ford dealerships. Otherwise most reputable car parts shops sell them. Also change all 6. Depending when you last did the plugs id also do those whilst your at it.

genuine are a rip off, though if you dont know what your buying your best to just stick with genuine from ford, i looked at good brands like vdo and bosch when it comes to buying ford electronic parts, because i know both are used by ford, basically your just buying the genuine part thats cheaper.

i used vdo coils in my car and it fixed my backfire upon start up.
they save you at least $40 on ebay going by the cheapest genuine ford coils x6 and the price i payed for vdo coils x6
