Hi,
In the interests of attempting to give something back to the forum I thought I would share my misfire misadventure.
Apologies if this is old news or has been covered before.
About 6 months ago my 2.2 CDX started misfiring on startup. Problem would last about 30 seconds and then all would be sweet again. Occasionally I would get a engine fault light and the code (read on an "ebay special" tech 2 handheld) pointed to a lambda sensor. While messing about trying to disconnect the lambda sensor (I am not a very skilled weekend mechanic) the fault vanished. Figured connection prob.
Mid way through the snowfest of a few weeks ago the fault returned except this time it would not return to smooth running at all. Engine would fire up, run for 5-10 seconds then die. Juggling the throttle I could just about keep it running but driving it was a nightmare.... 5-10 seconds of power, then virtually no power then power again.... so it sort of kangaroo'd until limp mode kicked in.
No codes (that I could read) so off to my fav Vaux mechanic who always bails me out when I can't find the answer on OOF!!
Turned out to be the mass air flow sensor open circuit.
Now my baby runs like clockwork again. Which is fab because I do love my 2.2 CDX estate (yes, am getting therapy for the problem!!
).
If anyone in the general vicinity of Camberley Surrey needs a good/dependable Vaux mechanic, message me for his details. Didn't want this post to read like an advert!
Regards,
john
