Help performance gone

[MLE16V]

fitted some MAGNICORE 8mm now feels like an 8 valve.

any ideas.

the std OE leads are of very high quality already and the 8mil ones might not be as good.

 

[Fred@BTM]

Are they all plugged in???? Are they all going to the right plugs?????

 

[steve_rt]

put the old ones back in and see if the performance re-appears - might have dodgy leads?

ive got 8.5 mm magnicores on mine and it runs sweet. id say take them off take the plugs out, check and clean everything and re-install.

...yes re-install, format then defrag.

the leads are good ones, check everythin over again as above

it wont be the leads performance, you either havent installed it right or have a faulty lead
