Hello all, this is my first post as i've just joined tonight seeking some advice.
I've had the same problem with my RCZ. Last night i started it up and whilst on
tick over the revs dropped to under 0.5 and when i pressed the accelerator there
was no response. Then we got the ding dong and hey presto "ENGINE FAULT - REPAIR NEEDED"
I left the car over night and tonight went to start it up and everything seems fine no drop in revs
at all so i gave it a blast up the road and the power is there nothing wrong with it. The fault is still
displayed but the car's performance is as normal. This is the second time this has happened.
The car was returned to the dealer 3 months ago and they told me they had replaced the ecu and since
then it's been fine. The car has only done 7000 miles in 2 years.
Today I phoned the dealer again to explain the situation and was told that i should be using super unleaded fuel
as the RCZ is designed to perform better on higher octane fuel! wtf? Is this correct? I must have missed that in the
handbook?
After that bombshell they decided they should have a look at it, AGAIN!, yippee!
If anyone can help with what might be the real cause it would be greatly appreciated.
All the best
Nick
