@SER_GTR
finally i connected following
bty to left shock
bty to engine head
bty to intake manifold
intake manifold to chasis
i also changed plugs to bosch 4 tip and changed air filter and mixed a bottle of injector cleaner in petrol and topped up my fuel tank
the results i achieved are
HP of car increased thats what i felt
there was no change in idling
Car start bogging when i move it from idle
petrol consumption dropped to 7 kmpl
Due to the problems i underlined i removed the wires and car is back in its original position
By the way why it start bogging that was the real point of my worry, coz of which i removed the wires, thought it may not harm the engine
Kindly once again some good suggestion
