I had tachometer installed couple of months back from Federal Autos IBD. Cost me Rs 1300/- including labour. Nothing major about it; they will install it in the same dashboard beside Speedometer where DAEWOO is written otherwise. No idea about the headlights but I always favour original parts.
Well I took the IAC and VSS out and I believe they are the one as in these pictures, right?
In red circle IAC and in black behind connecting pipes is TPS which I only sprayed with WD-40 as it was installed.
And here I believe is the VSS cleaned with WD-40
Vehicle had much improve idling for 2 days and then it repeated same thing. I must say idle RPM is steady and controlled but still erratic at times. Did not try emulator thing neither really understood it.Who would really check it by the way?. In the end I must thank you for your great help. Thanks
