High idle

Hey, so i know theres been a million threads about high idle but I don't know enough to follow the advice on those.
So my idles sitting at 1.5k all the time, for a while it would go up to 1.5k for a bit and then go back down but now just sits at 1.5k. in more detailed descriptions than on other threads (I don't know where things are) what should i be checking and replacing?

 

Might just be an incorrect reading. My car does the same and when I told my mechanic he found it rediculous that it idles at 1.4k and said if it actually was that high once you took your foot off the break the car would jump forward intensley. When he got to look at it he said the idle was perfect just the reading was wrong, I confirmed with with the previous owner who had tuned it previously for 700-800 at idle.

 

Nah its not that, it sounds high aswell.

 

go to the tech day on sunday.

 

Good idea, didn't even think of that because I was supposed to be flying north for work before then, but theyre having issues finding accomodation so should still be here sun.

 

Oh man... a zed that can idle properly... what a dream!

After I replaced my coolant temperature sensor, put in a series 2 PTU, replaced my 02 sensors and bypassed my det. sensor, my NA idled perfectly... for about a day...

 

Wish it were like my EB falcon where i just turn a screw

 

when did it go up?i sthis just after you changed for exhaust? time for a ecu reset if it only happened after exhaust

 

Nah been a while now, thought fixing exhaust leaks might fix it though.

 

Throttle Possition Sensor - TPS
Check the connection.

I pulled off the connector on mine and cleaned up the corrosion.
Fixed my NA from idling at 1.5k

Now idles at 750 perfectly

 

Where would I find this?

 

Side of engine:



The red arrow points to the connector.
If u pull it off and theres green corrosion, its probably ur culprit.
