running rough

[Fusion1]

Hi all had both my lambda censors changed 2 months ago, new clutch last week and decat pipes fitted and the car has started picking up real sluggish and feels like its missing, on the laptop lambda 2 is still playing up till the car is warm, throttle pots seem ok. Could there be a problem with the coil packs or leads or will having the decats fitted alter the fueling in any way, only stutters on acceleration but once moving goes like stink.
thanks

Are your de-cats linked? I was told that fitting a linked de-cat would require the ECU remapping too.

can you download both the adaptive maps? if one of them has all 0's in it your lambdas connections are back to front, this will give the rough running you mention.

Hi Fusion

I did have my coil packs and HT leads changed due to a poor running problem last summer and the car ran great afterwards. Whilst the symptoms sound similar, my understanding of these things isn't good enough to be able to say much more than that!

Good luck with getting it sorted!

well not geting any lambda faults when warm, but geting bad afr 2468 and adaptives are still runing close to 30 on bank 2, reset adaptives when warm and its ok for 5 mind then the afr bad comes back.
any thoughts anyone,thanks

Sounds like you need to set the Throttle pots up and balance the banks.

throttle pots are balanced spot on at idle at 19
