Help Misfiring So Bad Can't Drive R32 Gtr

[geetea-are]

I have had to walk home, I just put octane booster in my car and it has gone to shit, is it the o2 sensor, I was only driving it for 5 mins, it has a mines ecu as well, it was misfiring some times before this whilst on longer drives but no were near as bad and would usually stop after turning it off

Skyline's are not meant to misfire at all, contrary to popular belief. You have more problems than a Mine's ECU. 2 things might have happened with the octane booster 1. Destroyed either 1 or both oxygen sensors (I don't believe for a second when they advertise 'safe for oxygen sensors'). 2. Spark plugs are blackened.

You're not going to be able to diagnose the problem until you get a stock ECU in there and confirm it's not the Mine's ECU causing it. Otherwise I would be looking at the crank angle sensor, coilpacks, spark plugs & coilpack ignitor.

I think it is the ignitor as well, I when I touch it, it changes the revs, would I be able to just install the stock ecu? Or would it require a tune?

[geetea-are]

Is there any way to empty my tank, like a draIn bolt

Swap to a stock ecu and change ur plugs to bcpr7es

If it still misfires then coilpacks

Stock ecu is stock ecu. No need for tune.

Check plugs.

Drain tank by getting a suction hose into it. No drain bolt
