Omega General Help / A solution found to limp mode
« on: 25 July 2010, 11:48:52 »
Dear Forum,
I have asked many of you knowledgable
people about my Omega problem. Which
was in a limp mode after a new exhaust from
the catman.co.uk. The emmisions light was on
and as I've mentioned it was in limp mode. I have
a 2.2 Cd auto saloon and have been plagued by
this problem for 3 years!! If you have the same model
as me don't waist your time time trying the paperclip
test or the pedal test as they don't work on the 2.2 model.
If you have this problem an you need to use your car, disconnect the first O2 sensor, let the engine warm up
until the fans come on and re-start the engine, now you will
know if it's out of a limp mode by pressing the sports button
on the gear stick. If the light stays on you know you can drive away, but you don't have to keep it in sports mode. This is not a permanent fix, but it will get you home.
Back to my original problem, once I understood what an O2
sensor does I decided to tighten up the manifold and exhaust
just incase their was any leaks, yes the O2 sensors really are that sensitive. My manifold was loose, a quick tighten with a 13 mm socket......job done. My point is this Forum is Gold,
I would like to thank everyone who has helped me sent me links etc.....I have saved at least 200 quid, as I was going to buy 2 new O2 sensors and maybe a fault finding mission at my local garage. If you take into account the local fast fitting exhaust company quoted me £700 quid to replace just the exhaust and cat. I did it myself for £260 + £3 for paste with a trolly jack and axle stands with a basic tool kit, no power tools, oh and penertration oil......many thanks to you all and good luck..
