R34 Running Werid

[ian_and1]

Just wondering if any-1 can shed any light on this for me

sometimes randomly out of the blue when i turn my car on or while ill be driving it will drop RPM slightly the TCS and SLIP light will come on also i think it's the ECU light (lil square orange light on the top right hand side of the dash cluster) and it will start to idle/run weird sounds like it has dropped a CYL sound basically sounds like a WRX. Have checked/replaced coils and it only does it some times, it might not do it for a month or so then it will do it again :S

please help

perhaps reset factory ecu first, sounds electrical so re-check plug, wires etc

does it run rough

if so check your coils

Do a self diagnostic test on it by bridging two terminals on the data link connector there is info on here somewhere as to how to do it, bridge CHK and IGN with the ignition on, mil light will most likely flash a code 21 = no consecutive ignition signal with engine running meaning coil pack.

thanks heaps it's just got me stumped as it only does it some times :S if i tried the self diagnostic when it was running normal would this still show the same problem as to when it was running crappy ?

just had a thought. about a month or so ago a KKR 430 was installed (dont ask why ) now could that be causing some of the problems that im having?
