Hi,
As you all know i have swift Vxi from jan2007, till date odo shows 16500km's, at the 13,5oo km's above said problem started, i am the slow driver, i start move at 1st gear upto 10-15 km/h then to 2nd, between 20-25 i will move to 3rd, after 45 i will change to 4th, after 55 only i will push to 5th, Engine jerk[as per Mr. Lokesh, suraksha] start's at 3rd/4th gear, it's like cutting/stoppage of electrical supply to the spark plug for less than a second, it will continue for few jerk's & will be normal at high speed.
On 8th of Mar.[at 15144km's on odo meter] at suraksha, they changed the all Spark plugs, & 2 no's of DDIL COIL POLE Joint with spring[pole with plug connector] in the test drive itself i found that the problem disappeared & become normal condition.
Last saturday i went to Horanadu-shringeri long trip covering arond 750 km's, for 2 day's, while coming back in the slow traffic,[after dasarahalli] i started feeling above said problem again

and got few jerk's in last 2day's in city traffic,
Is thier any other TBHpian who own's swift & got like this problem?? or any suggestion please.........
