grannyknot Posted July 16, 2021 Report Share Posted July 16, 2021 Finally got the engine running consistently, idle is about 900rpm, can't seem to get it lower without it starting to stumble, advance at idle is 19 degrees but when I blip the throttle the revs go up to 1200-1300 and hang there for 4 seconds or so before backing down to 900. The throttle cable isn't hanging up anywhere but the revs are. Does that sound like a recognizable symptom of something? Thanks Quote Link to comment
Drummerboy4as Posted July 30, 2021 Report Share Posted July 30, 2021 Are you using an auto ECU by chance? I’m trying to diagnose a similar issue and I’m reading auto ECU’s may do this normally. Quote Link to comment

No, I confirmed that the ECU is from a manual car, since that 1st post I have managed to get the idle down to 800rpm but it still hangs. After a bunch of reading here, and the Zilvia forum it seems to be something these engines do, some don't have the problem but it is a common complaint. Quote Link to comment
