title says it all really... recently had new exhaust, 3" downpipe and decat into 2.5"
This started to show a couple of issues with the car, slightly rough idle ( cleaning TB sorted this)
loss of power (downpipe bolts ended up loose, tightened these up and ok again)
Occasionally once the car has warmed up i get some grey smoke from exhaust (i can only assume car is overfuelling and thats the unburnt fuel and condensation in the exhaust getting burnt off?) unless it was leaky valves hidden by the cat but im not losing any oil and any smoke isnt on the overrun but on boost and only once the car is up to temperature
The thing i dont understand is very occasionally, when slowing down to come to a stop, when i still moving and i put the car in neutral it sometimes cuts out, i look down and just the battery symbol, turn the key and it starts fine.... garage seem to have no idea, just wondered if anyone has had anything similar?
On looking round the engine bay only thing which is obvious is the staining round the injectors but can't imagine that would cause the engine to cut out..
Only fault codes i have are for lambda and knock sensor but have been told by Seat these codes are the result of the decat and here as long as the car is a decat.
I want the car remapped but ****** and Badger are a good 3 hours drive away, dont want to go all that way only to be told i have some major issues to fix first..
Thanks for taking the time to read, a little vague i know but any suggestions or advice is much appreciated
