hey guys,
i have a problem with my rb30, it runs fine when its cold, but when it warms up, it has a serious miss, has no power and when i accellerate it looses power and wants to stall,
i have replaced the following:
air flow netre
cam angle sensor
plugs
leads
coil
cleaned out the injectors (profeesionally)
fuel regulator
intake pipe
fuel pump
fuel filter
drained my fuel tank
blew out all fuel lines
got cracks in my exhaust welded up
new catalystic converter
new muffler box
new o2 sensor
cleaned out my air filter

and its still doing it its driving me crazy

Have you tried replacing the plugs on all the sensors and dizzy? Common RB30 problem, all the plugs just get shit and crack and all become loose and have poor connections. Also the ignition module in the dizzy could also be the problem or the ignition coil even.

brand new dizzy aswell, connections are fine.. ignition coil is brand new, so are all the leads and plugs

My thoughts are that if you have replaced all of that, check to see if the ECU has had water in it, which is common to leak in from the windscreen.

So all the plugs for the sensors are new, and the pins aren't dirty or corroded in the plugs?

crank angle sensor?
try the throttle sensor, un-plug it and see if its goes ok
thats what i had in my 31
but its basically just all the wiring getting old so as someone said, get new plugs and wire them in

I could wildly adjust the quality of idle on my R31 simply by moving the harness that went to the injectors,Im not talking about reefing on them,Im talking about wriggling it with my fingers!!!
Turns out the wwhole half of harness on that side of the engine was brittle ( from the heat I assume) and played merry hell till I replaced it!!

Might not be it as its a problem once it warms up I guess,but DEFINITELY something Id look at ASAP...Start it up and get in there and move the plugs/harness around....You will be able to hear something if there is a problem somewhere

also sheck all ur wiring at the rear of the car, like tail light loom all the earths to the body and the fuel pump wiring aswell, jus make sure all the wiring is ok inside the wrapping and again check all the earths have a good contact.
