Brand new Splitfire misfire (r34 GTT)

Recommended Posts

As the title suggests, I just bought brand new splitfire coils from just jap as well as a brand new genuine coil loom. I bought them because I was starting to develop a small misfire but also have my tcs and slip lights on and was informed by race pace that coils would fix it. After failing to fix my tcs issue my car now has a pretty serious misfire. The spark plugs were replaced very recently too so they are fine. Any suggestions on why the misfire would be much appreciated, and any information on the tcs and slip lights would also be super helpful

Find out what the fault codes causing the lights are and you will be well on your way......

Tcs and slip lights don't have fault codes. And the lights didn't change after I changed the coils. I just ended up with a massive miss

They do.  You can use ANY decent scan tool to pull the fault codes out of ALL the CUs in the car.  That's ECU, TCU, ABS/TCS and HICAS.  There are even procedures* for putting those CUs into diagnostic modes and the idiot light on the dash will blink the codes at you.

 

*that involve turning around three times with you hand on your head, shouting "Wiggle wiggle wiggle" and doing 5 star jumps while reversing slowly at <1 km/h.

I have read the manual back to front and to only way to read error codes from the abs/tcs is using a Nissan consult device, not just "ANY decent scan tool". The method for bridging two pins to get into diagnostics mode doesn't work for TCS. Unless you have some magical method for doing this which I would love to hear about

I've done it myself using my mechanic's generic scan tool (ie, workshop quality, just not a Nissan Consult only unit).  How do you think workshops diagnose this stuff?
