Idling at 1500rpm

Recommended Posts

Have an issue with idling at double what it should be. The ecu is in a WRX V5. Running a G1 possumlink

Can any one suggest what or how to change the idle speed and hopefully bring it back down to 750rpm. 

Also when throttle is pushed it seems to stick there for a second then slowly come back down.

One possibility is that the throttle cable or plate is sticky. This could be causing the throttle plate to not return to the throttle stop position, and so extra engine flows into the engine causing a high idle.

Ok so have that sorted throttle body cleaner fixed that though now its coughing like I have an exhaust leak which I dont, how do I tune the Link G1 ecu to get rid of this issue?

Does the coughing only happen at certain engine speeds or loads? It is hard to know what the solution is without doing some diagnostic work to find the cause of he problem. 

Here is the manual for your ECU:

You could check the voltage output from the TPS (into the ECU) and see if it changes when the throttle moves. If it does not then the fault is in the TPS or wiring.
