I had the same problem with my wife's Honda City IDSI year 2005. Went to the local mechanics and he confirmed it was spark plug coil's faulty but IDSI has 8 of them and he can't check which one fails, the cost is RM160 each, total cost will be RM2K plus, the local mechanics didn't want to change for me fearing if the new spark plug coil is faulty, he can't bear the cost and give me warranty on it. He suggested me to go back to Honda SC.
I was lazy and bear with the jerking for about 6 months, and finally during this year CNY, went to HZN Honda Service Centre in Glenmarrie, left the car there and the free shuttle service sent me to Empire Subang in the morning instead of me waiting there. In the afternoon, the free shuttle service came and pick me back up and I waited in the SC for a while more, and finally they have found out that the spark plugs that I have replaced last time is Denso brand and Honda is using NGK (if I remember correctly, or could be the other way round). Anyway, they went ahead and change all spark plugs and the cost was about RM130+ and come with a free car wash, and free unlimited milo and nescafe.
IT solved the problem, till now there is no more jerking.
Honda SC said they follow the procedure, change the spark plugs first, since it is not according to their specs, if that fail, they will change the next thing and so on.
My car same problem with TS.
Wanna balik kampng for CNY this week....
wanna ask, so after changing the spark plug no more issue? No need to change the coil plug?
