hello just joined an first town car bought couple weeks ago 146k drove great but recently noticed hesitation after 30 up to normal speed limit. ive read many post on here and other sites but it is overwhelming trying to figure some sort of direction, what i have done myself is motor craft plugs, 8 mid grade coils because motor craft brand are so expensive also a new egr valve. im going to replace fuel filter soon. any other ideas maybe sensors? thanks for the support.
