Update: having cleaned and lubricated the throttle body and thinking this had solved the problem, it came back again. I put a new throttle body on and immediately had a smooth tick over from cold and it would seem much better fuel consumption. I even saw 36 mpg as an average from Surbiton to Rushden and back, well pleased with that.
Finally sorted this problem (I hope!) Turned out to be a sticking butterfly in the throttle body, cleaned it all out and lubricated the butterfly and all is well. Now I have done this I wonder if there would be any benefit in putting on a new throttle body, or should it be ok now?
The red lights flash in the remotes, so they are working. Thanks DG,I’ll give it a try. Doesn’t seem to be any pattern to this. Intermittent faults are the worst kind! Boot release is hit or miss too.
I now have a problem with my Omega where it sometimes locks or unlocks with the remote and sometimes doesn’t , I’ve changed the fob battery twice in two different keys and now have a new main battery but this hasn’t solved it. If I unlock it with the key the sounder and alarm go off until I start the engine - not ideal. Any ideas?
