Rb20det Running On 4 Cylinders

[GTS4onP]

Hey,

My GTS4 is now only running on 4 cylinders and i dont know y?

i was thinkingmaybe 2 of the coils were stuffed but i dont know how to check them, i know the sparkplugs are near new so dont think it will be them as theyre denso iridium ones aswell

any help appreciated, cheers

You should take it to a mechanic, as dropping cylinders / faulty coils is an exceptionally rare occurrence with Skylines.

All the best

lol im sensing a bit of sarcasm there as i know that coils are a common problem

just would like to know how to check them though

your less then an hour away from knowing how to test spark and fuel.

ive had a rb20det with the same issue it end up being the resistor box for the 1st and 2nd injector. wriggle the wiring harness going into it and see wat it does.... either way the fix was a new res pack as soon as it was plugged it all fixed. just check that aswell

ok sweet, ive just had my mate over and we checked all the coils, turns out that Coil #2 was shot, so now im looking for a new coil. hopefully that fixes the problem

if not ill be back here for some more help

cheers

read up on wasted spark before you splashing out on new coils dude. its a good alternative as is immune to the issues the direct fire coils are suseptable to.
