Common Peugeot Idle speed problems

The Peugeot 106, 206, 306 & 406 with the 1.4/1.6.1.8 litre engines have a very common problem with stalling at traffic lights and eratick idle speed. This is usauly always caused by the ignition coil pack going high voltage and dammaging the sensitive electronics inside the engine control unit (ECU)

 The original Sagem coil-pack should be changed for the Bujicord coil pack this is a revision made by Peugeot in an attempt to resolve the voltage spike problem. Normally the coil -pack will always damage the ECU

Symptoms include:
Misfiring
Poor idle speed or stalling
Hesitations during acceleration
