Low Idling RPM.

[mosesmk]

Dear All

My inspira suffer low idling rpm when car totally stop and in gear (D/R). 1st mechanic say it cause by my bad engine mounting. His right, engine mounting already in bad shape. change it, yet not really solve it. Idle still around 7++ and lower is 500 when idle in gear. Just need some opinion because they saying few thing could lead it.
1-Clean the throttle body- just spray the butterfly. Will totally dismantle TB soon for service.
2- Spark plug.
3-Vacuum leak.

Does anyone got this kind of problem?

You pretty much covered all 3 suspects. I don't know how it works for Inspira, but after you replace and check those things consider resetting the ECU either with the Proton diagnostic tool (and clear errors) or try unplugging the battery overnight

Why would the mounting increase idling? To what I know, bad mounting gives you vibration.....

no idea. when he start my car, engine shock a bit and he say engine mounting faulty and lead to low idling. last time with my manual ride, bad mounting cause bad vibration when speeding.

Yup, mounting to absorb vibration. Damaged mount cannot do that so there will be greater vibration, not low idling....

ECU reset with a handheld obd device will fix it. need to go back to the place that u did the remap so that your current map doesnt get wiped out.
