Engine management

[lewis89]

Engine management light on then off
Car drives fine for a few miles and then once stopped at some lights, then engage 1st gear and pull away the car like jumps then puts engine management light on then goes off after a couple of seconds and car drives fine?
I know this happens when cam sensor fails but that usually ends up with the car stalling and it's not doing this. Plus I did buy a 2nd hand cam sensor last year and all was fine.
Also pinned 1-4 on obd and no fault codes being given?
Any advice, thanks

You sure their is no fault codes?

Possibly no fault codes because it's stalling and putting the engine light on. Which is the hesitation/jumping effect...

Tbh I don't think the car does stall. I had a new clutch fitted the other week and read it could be something to do with 'knock'

Twin plate?

 

[RsvRob]

You read it could be knock because you just had a new clutch fitted.
Engine light wouldn't come on because of knock unless it's mapped on. It's not a std feature.
Even a correctly installed twin or triple won't cause it to trigger knock sensor.

Ive seen a few new twin plates cause cel on knock with ceddy

Not twin plate. Standard evo 7,8,9 with bigger flywheel. I have a evo5.
Not sure if it was mapped with it, will have to ask my mapper but just trying to rule out what it could be and only come across reading about the clutch causing 'knock'
Cheers

Not the engine running badly due to poor fuel or anything then!!
