355 plug leads

hello chaps, since i bought my 355 2months ago i have had what i describe as a misfire, in that when i apply throttle or at tick over the engine does not run even and you can hear warbling sound ,now the fcar has gone back to the dealer i bought it from (specialist) and from him went to an official ferrari dealer for what i presume would be full diagnostics.when i got the 355 back i was told they had replaced the plugs (even though i had replaced them myself 1 week previous) and one plug lead and the cannister for i think is vacuum/emission controlled which had rusted away,when i drove it away it was slightly better but the problem still their,i have enquired about changing the leads and now realise why they only changed one (£125. each) i have rang round and found full set for around £300 but still a lot to pay on the chance that it may be the other leads,does anyone think it will cure the problem or is it something else i should be looking at before i purchase the leads and is their a cheaper option lead wise ,your views would be appreciated.steve

 

cheers bud i will see if they will ship to england.more realistic price.

 

i have sent email so hopefully they will reply soon.do you mean the airflow meter with the 4 connecters and screw on type fitting(mine a 5.2 with one meter) if so i have cleaned and checked it.
cheers steve

 

hi,yes have seen those ,there typical fiat connecters which are a bit fiddley to remove ,i think the best thing to do is clean everyone you see on the motor and check them for corrosion or damage and at the same time lubricate them to avoid damp.cheers m8

 

thanks ernie,i guess when you have a problem you always expect the worse possible cause,when quite easily its something quite simple to fix,well hopefully it will turn out to be the leads as im sure their the originals and from the heat in engine bay they must be all past their best.i will ring the lead company tommorrow if they dont reply to my email .
