This is common problem......................... rough idle, not boosting, misfire, black smoking, bad fuel consumption, etc....
Why?(**)`
Must be ....................
................ coil pack or ignition coil.
Especially CA, RB25neo, RB26(R34gtr),SR2odet( S15)
Normally one coil is getting bad, and you change one, next...... another one getting bad as well..
So if you have this problem, change them all in same time to blue one .
Actually, It's cheaper than factory anyway.....and more power!!???????
Need test?....................................... Dyno run............. anyone wanna try??
