Vacuum Hose Connection

Hello Dr-DJet,

Thank you for your advice.
I will check again if my throttle valve body has two ports for vacuum an retard.
Also I will check the ignition timing with following to your procedure.

Again thank you,

Hello

I posted high idle and idle hunting at D rage (Not at N range) before.
I would like to share with you that they have gone by replacing Trigger contact.
The contact I removed from ignition distributor has certain bent of the contact plate caused by worn it out 

Since I replaced it there is no idling issue anymore.

Best Regards,

JUN

Hi Jun,

that looks very bad. Like somone broke off a part of trigger contact and fixed it provisionally. If TC signals too many contact closure on both sides, ECU will think of high rpm and increase fuel. However that should not increase real rpm.

Hi Dr-DJet,

Thank you for your comment !
Understood, again thank you for your usual excellent advice !


Best Regards,
