Ok,
My idle on start up is about 1350rpm, hot or cold it doesn't move from there.
Just idles fast regardless. Does drop back to about 1000rpm in drive.
Things I've tried, clean and inspected ISCV, resistance test according to manual.
Tried 3 different ISCV'S ( these all worked on another car fine)
Tested for continuity between plug and ecu loom of ISCV.
New ecu temp sender, and check for 5 volts, and grounding to ecu
Tried two different TPS's, and set both according to manual.
Cleaned and inspected throttle body, made sure throttle plate was 100% closed
Check for air leaks, vacuum lines etc
Checked for airlocks in cooling system, vacated air through filling port.
ECU reset, check for fault codes.
Have run without iscv connected = idle was worse, and much higher
Without temp sender = no noticeable difference
without AFM, idle slightly lower, but not rough
Occasionally the idle has come back down to around 700 rpm, but not for long then it will go back to its 1300-1400rpm, not surging just steady.
I removed the ecu, checked for anything obvious, it has had new caps about 6-7 months ago, but was perfect after they were done, and no problems prior to either.
Anyway, the car runs perfect otherwise.
Just about over this now though, the only thing I can think of is the ecu has had enough ?? might be the next thing
