overboost sensor faulty?
« on: 00:43, Sun 26 July 2009 »
Just bought a new 5 and it's running quite odd but while reading other posts on this forum noticed that some people have mentioned the overboost sensor can cause a missfire if it's connected with the two wires the wrong way round. Is this true?

The engine idles really rough and needs the choke on, when you remove plug cap number 2 or 3 the engine continues running the same (rough) but when you re-connect the plug lead the engine sounds smoother for about a second then dies. I'm thinking plugs, leads, cap and rotor arm.

the over boost wont affect tickover that works by reaching a certain pressure ie 1 bar then cuts the power to the aei unit. as you mentioned check the basics like plugs leads rotor arm ect.also valve clearances
