hi all,

new user needing some help. got a x reg fiesta zetec s which isnt running right. basicly its slow on accelerating and makes more induction noise than it should do. prime example would be when i was driving on m6 the other day at 70mph in 5th gear, put my foot right down and didnt gain anymore speed, then slowly took my foot off the accelerater and started pulling away.

ive had the car serviced, new cam sensor, new coilpack, new leads and done compression test which was arround 250psi on all but still no joy! so if anyone has expirianced something like this before or might no what would cause it please let me no.

lee.
