Hey guys.
I have a Nissan skyline R33 S2 and the problem i have is when it comes up on boost around 5000 to 5500rpm it starts missing and breaking down. It does it on low boost (15psi) and high boost (20psi) Things i have done to try and fix it are new coil packs, cleaned Z32 airflow meter, new spark plugs (correct gap) injectors cleaned and re kitted, new fuel filter and cleaned air filter..
PLEASE HELP..
Thanks very much.
