So I got the RB running but now its making a weird random clunking noise at idle... I cannot figure out what it is but heres what im running. Stock RB20DET, N60 Maxima MAF (J60 MAF on way soon...), Seperate Temp gauge (temp sensor for harness is chillin exposed to the air), FMIC with 2.5 piping. It will idle and sometimes it will make a quite lound clunk, sounds like a metal on metal sound almost in the lower part of engine. It does not do it under throttle? So if anyone had any idea or suggestions it would be great.
