Vacuum leak..

[REDDYZ]

Throttle hang + Poor mileage + loss in power = Vacuum leak.

After doing such and extensive work on engine I was thinking what could possibly go wrong in near future? Well, its hardly a month I had good time with my kat without any hassels. Now there is a vacuum leak somewhere thats drawing excess air while idling causing rpms go over 2500. Searched everywhere for leaks but no luck.

I could hear the leak but couldn't find where. Wasted a spray can of contact cleaner but couldn't trace the leak. By passed oil catch can but didn't make any difference.

I don't know if it is co incidence or consequence day before yesterday I found instrument cluster and dvd player were reset on its own. Then after a while it happened again. After a bit of investigation I found the accessory cable on positive battery terminal was loose. I couldn't figure out how that happened. Couldn't make it tight or loose. Eventually I snapped the bolt and bolted that cable on the main bolt that locks terminal onto battery.

Since then idling has changed. Every time I depress clutch or shift to neutral rpms goes over 2000 and drops down after few seconds. Mileage has gone from 8.9L to 14.5L. Replaced IACV and disconnected TPS plug while engine running which didn't made any difference. I think its time to strip things around engine..
