Aoa i tested my 4 cylinders of my car honda city 1999 with d15b2 engine yesterday then mechanic told me 4 cylinder have low compression of 110 psi ... it was shocking for me though car is old but no smoke no water reduction no bubble in radiator no oil burning and reduction.... even i used to drive 90km/h at 2nd gear in 8-9 seconds ....then what could be the issue ? test was done after valve clearance and throttle body cleaning but engine was cold at that time and i dont know mechanic opened tha throttle or not ... is it possible to get low values with engine conditions? or something went wrong
second : tunning k bad car ko accelerate kero to pehle 1 sec ka sans ya stall type kuch behave kerti hai aur phir acceleration se nikalti hai .... what could be the issue ?
NOTE :: during tuning parameters are set to:
spark advance at 16 degree and
intake valve : 0.008 in
exhaust valve at : 0.009 in
