please can someone help me??
i have bought a fiesta rst that has been converted by ian howell at area-six, it is a 2.1ltr zetec silver top, running 300bhp.
the problem I've got is when the engine reaches optimum running temp it starts too miss-fire and splutter then cuts owt when im moving. then when i try too restart it i turn the key in the barrel 1click too prime the injectors and soon as i do that theres a horrible clicking sound like an electricity arc, but its not constant its intermittent and random.
the car will start but surges and bogs its revs down ticking idle.

i will really appreciate if you could shed some light on the problem or point me in the direction of a competent trustworthy tuners
thanx lads lenny
