hey guys, i changed all 4 spark plugs today for my 03 jazz L15A. i got those plugs from burson and all the same model as factory ones, the ngk iridium.
after the change, i noticed there is a huge power loss when i hit the gas hard, or going higher rpms. when i drive easy down lower rpms, the car runs better, like it normally does. when idling, the car randomly SHAKES, like a big subwoofer inside the car.
could someone have any idea what the problems could be?
im planning to change them back to old ones for a try tomorrow.
thanks in advance
regards
totti
