Corolla-99 Jerking when accelerate
Hi Guys !
I have a corolla 99 full automatic 1.6 XLi. I gave for some service and the technician washed the engine with diesel i belive. Well now i feel the engine is not smooth and feel jerks from it. When i accelerate i feel that the car speeds up not smoothly as it used to do in the past. At about 80 km/hr the jerks in the car are very prominent.
Any suggestion, what to look into.
Check you electrics for moisture, especially the ignition leads, coil, etc.
The problem got sorted out when the four spark plugs are changed with new ones. However i am surprised, since the four spark plugs were only changed 2 months back / 3000 km back. And i m told by Toyota service centre that spark plugs need be changed after 10,000 km, any suggestion what caused the early burnout of those spark plugs.
Anyone can point me to technical documentation for corolla 99 model.
