How can u test the tachomitor on a fiesta mk3. i've taken the console out and run a tempory wire from the coil on to the pulse leg, run a temporary earth wire and live wire and still won't work tried new tacomitor, i've come to the conclusion of it being the suppressor thats packed up or the coils packed up, even thow car runs obviously car does seem to pink a lot so i think the coil is weak anyway. is there anyway to test these, and where is the suppressor located too.

Cheers guys. BAZ
