Gday guys,
I got an rb20det in an r32 that is giving me a problem.
At idle it is surging between stall before it rises to normal idle at 700 and does this continually and sometimes stalls, this has became ever increasingly annoying in town driving as it stalls when you put the clutch in and while its in nuetral.
If we disconnect a vaccumn line and let it suck straight air it returns to a normalish-high idling range but with no surging.
ECU shows of no error codes.
Driving me insane, anyone got any ideas?
Regards
Stan
