Well dear it feels better, not that much as I expected:
1. Pick has improved a little (maybe there is something to be done with the valves (tappet), input required from members)
2. Missing at higher gears & low RPMs has considerably decreased
3. First cranking of car is still longer (members tell me what needs to be done ?)
4. Exhaust used to throw off a lot of unburnt patrol on cold start, the same has significantly decreased !
Btw anyone knows of a place from where I can get sensors cleaned and valves (tappet) adjusted reliably and cheap (Karachi) ?
Anyother suggestions are welcome !
