The check engine light....
Discussion
I've done a search on this and it seems some of our cars are prone to having this come on for no apparent reason. Mine is one of them. Has anyone got to the bottom of this?
Mine comes on from tine to time and can be cleared by prodding the computer mode button. The car always drives fine through the whole episdoe. When logged no fault codes come up.
Suggestions I've heard so far are maybe a faulty 02 sensor, or perhaps a dodgy plug causing a slight miss once in a while.
I don't think anything serious is going on, but it's certainly annoying.
So has anyone had this and actually fixed it?

Yeah get it scanned to find out to make sure its nothing major. Like Roger says its usually an O2.
If you are coming to the Ace Ill scan it for you. You can turn off the MIL light on the dash for most/all DTC codes, but sometimes its best to know something is up.
Dodgy cats and relocated O2 sensors can throw codes for various reasons. Usually insufficient/lazy switching due to being too cold. Or with no cats, it will complain about being too rich post cat.

I suspect mine is the latter then as it de-catted. I'd take you up on the scan offer cos the ACE is not so far from me, however, I have childcare issues, so I prolly won't be able to make it. I'm up at Monkfish next week getting some new discs, so I'll see what they reckon when I'm there. Thanks for your help.

Can I take you up on that offer Rich, just to make sure nothing else is wrong. If you are coming to the Ace Ill scan it for you. You can turn off the MIL light on the dash for most/all DTC codes, but sometimes its best to know something is up.

No problem unlimited scans available for free 
I can also show historical codes in case you had a warning light before and now its gone. You can still see what it was.. unless you reset the ECU by pulling power etc.
Plus I can clear them again for you if you like. Just let me know on the day.

mine does it if ive been over enthuiastic when cold and hit the limiter!
some times it goes reduced power but is cleared after a stop of more than a minute or two

Whats this reduced power thing when the car hits the limiter. Mine looses no power at all. Just beeps at me and sign comes up to change gear. Never had an power reduction

Ever heard of warming the car up first!
Oh sorry, i didnt mean when the cars cold, I meant when hot. I never go over 3000rpm when its cold.
I've seen it on here a few times now. People mentioning they get reduced power if they go over the red line. I've never had that. Was it something on the earlier models?

if i can make it down could you fit my supercharger, download the base tune from the spare ecu, upload the saved parameters to a new custom OS and install a valet mode for me before tweaking the tune to get it just right? All for say 6 bottles of ale? Would ask you to fit the LS7 clutch and the wideband sensor for me and set it up while you're at it but dont want to take too much of your time
