hoping someone can help me.
my car is fouling a set of plugs about every 250-300km, and when i replace them they seem to look different?
cylinders 1 and 5 seem to look good, but the rest are completely black and fouled.
i had it tuned about 1500km ago, and it had a missfire, even when free revving. the tuner suggested cam angle sensor, but i have tried swapping it and still no good, then they suggested i get my entire ecu rewired?? however i dont think that would be the problem as i have talked to the person who tuned it when it was first rebuilt and he said the wiring in the ecu was done well.
the car is an r32 gtr, with fully built motor and trust t78 turbo, with 1000cc injectors, twin bosch 044s, ems 8860 ecu.
the car has splitfire coils, but i am guessing they are as old as the rebuild, which was 2004, are these known for failing. is there a way to check them to see if they are working fine??
any help would be hugely appreciated as i am looking at taking the car to a shop to find the problem, which i guess would be rather expensive. definately if i have to get my ecu rewired.
cheers
