Oh and don't forget all metal expands under heat so sounds like spark plug gaps

mine only happens when cold soon as the engine warms up roughly 3-4 minutes the issues dissapear and runs perfectly fine.

Well, if i get the problem fixed Adam i'll let you know.

I've done a quick video today, sound is a bit toss but at around 20seconds the car sounds its worst, the rest of the time it's a bit less violent than that.

Mines ruff as anything I thought having my remap would help it hasn't I cleaned my throttle body which was manky as hell this cured it for a while but it's back to lumpy jumpy also my starting issues have returned sometimes starts fine others need some throttle to get her going!!! My mechanic gonna start eliminating things for me now, thinks it could be fuel related as in it's notngetting the right mix!!! Bloody cars always something, I've got a terrible ratltle too had heatshield tightened its not that now been told its my flexi pipe rattling grrrr just had new clutch master and slave cylinder and driveshaft seal replaced then my discs and pads needed doing only had the car 9 months over spend about 3k on it ha ha

chelle, looks like you just purchased the car at the wrong moment...

if i was you i'd look at temp sensors and ignition systems before going into fuelling.

has anyone tryed resetting the ECU?

when my 1.4 split a coolant hose i needed my hazards and sidelights because i was in a dangourous situation, this left my battery flat and the ecu of course couldnt maintain its memory... after that though the flat spot i did have at times for overtaking never reared its head again and i had power all the time... Took me 30 minutes of driving to get it to idle again as it forgot how to idle and just couldnt do it!
(what im saying is disconnect the battery with your light switch on and make sure any system in the car is dead and re-connect after 24 hours turn all switchs off before re-connecting battery though)

I have listened very carefully and can now hear the pause in the idleing, could be coil pack on way out, does it actually misfire properly or just that tick over "RRRRR" "RRRRRRRR" ?

It just does that really, keeps sounding like it's going to stall. I did email Simon today (I said it wasn't anything to do with the kit) just to see if he had any insight.

It's going on a dyno on Tuesday to see what this 165 kit is putting out, we will see if this problem is doing anything else further up the rev range but I don't think it is.

Nah he didn't. It would be quite hard to diagnose over email I guess.

think it's central email so needs to be made for his attention think.

My battery was disconnected recently when my clutch was fitted - only know this coz my radio code needed reentering!! Same thing? Or try again? Cheers and yeah i spent too much cosmetically my own fault didn't think of under the hood lol, she 6 years old and 73k so expect things to start need replacing!!!

Adam do you get a distinct smell of unburnt fuel when this is all happening?
