Sean S Posted September 23, 2016 Report Share Posted September 23, 2016 (edited) Have an issue with idling at double what it should be. The ecu is in a WRX V5. Running a G1 possumlinkCan 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. Edited September 23, 2016 by Sean S Quote Link to comment Share on other sites More sharing options...
Scott Posted September 23, 2016 Report Share Posted September 23, 2016 (edited) 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.Scott Edited September 23, 2016 by Scott Quote Link to comment Share on other sites More sharing options...
Simon Posted September 26, 2016 Report Share Posted September 26, 2016 Also check for air leaks any where between the butterfly and the engine. Quote Link to comment Share on other sites More sharing options...

Scott Posted September 29, 2016 Report Share Posted September 29, 2016 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:http://forums.linkecu.com/applications/core/interface/file/attachment.php?id=2531 Quote Link to comment Share on other sites More sharing options...
Sean S Posted October 18, 2016 Author Report Share Posted October 18, 2016 Hi Simon, throttle position is at 50% and unable to change, so it runs extremely rich. Any suggestions? Quote Link to comment Share on other sites More sharing options...
Scott Posted October 18, 2016 Report Share Posted October 18, 2016 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.Scott Quote Link to comment Share on other sites More sharing options...
