I brought the car in 2013 august. it was brand new pin pack. I was lover of 8th generation civic because the 9th generation civic didn't apples me. I love to drive that car I maintain my civic very fine, just like original lubricants and filters.
my car drive was very smooth light or can say excellent acceleration, but when my car reached 35000 it started problems and the paddle of my civic was very hard. very bad acceleration, so I passed from very painful time period, my car reached at 40000, nothing improved.
some told me change the fuel filter, I search on internet. and replaced it I feel 20%diffrence.but very disturb, I made valve adjustment and throttle service and throttle calibration. 5 % improvement, again I was very disturb that this was not my reborn who just booms, then some one told me that change the torque foundation, I was so irritated that told them that change it when they uninstall the old one it was quite ok, but I ignore it , I feel some change some where 10%, but the excellent acceleration issue remain same. I think my be the machine get older it drops its performance. I think I should sell it, I went to my car mechanic who was known by good valve adjuster,i told him to inspect the valve again and make throttle calibration, during this process my car also start blowing sound from engine booomm booomm when I give 3000 rpm, oo man what the hell is going with my car, I was literally sick, at night when I was back from workshop I start studying about catalytic converter , whole night I study it and in Moring I plan to go Honda pit, and request manger to just unplug the catalytic converter and hand over to me, I my self will clean it, i used the paint brush and enter from first sensor hole and clean the surface and insert the air pressure from second hole it blow out dust air, used the vacuum cleaner and air pressure it take one hour contentious cleaning, after that the boys carefully reinstall the catalytic converter.
i give the start, but guys when i drive my car , my orginal acceleration was restored, feb 19 2016 was the lucky day to get rid of the problem, i took my car to moterway it was extremely smooth , all the bad sound was finshed, the engine was behaving perfect nics sounds, so once again i was in love with my car.
