i recently got my plugs changed to NGK single tip stock plugs..previously i have been using the bosch 4 tip FR78x,which were givin me quite satisfactory performance and economy on CNG/petrol...
secondly i'v been using zic A plus ,and now shifted to MOBIL now on a mechanics suggestion..now the thing is,i have felt a huge difference in the pick up and fuel economy both,on cng and petrol,the car seemz to get breathless,even if i pedal it to the floor,the response is really poor..and now the car is almost refusing to climb up steep slopes,tried hard to get to monal,but could'nt!!
what can be the possible reasons!!got the tappets and throttle body cleaning done by honda guys a couple of months back and i dun think there is any issue with that..
i was havin a vague idea that i have upgraded my audio setup recently,and the electrical load is too much on the car,if that could be a possible reason??
neeed ur help experts!!:(
