I have a 97' lancer with the 1.6 engine, here's the thing, when I press the accelerator slightly it jerks a little no matter if Im moving, or taking off from a stop, If I press it more, like doing a more sporty driving its ok, doesn't do that, the rest of the time works ok, except from the rought idle it always have. Things I've made: -Spark plugs check -Coils and cables check -EGR check -Cleaned the whole TB and Iac valve

It has a manual transmission

  • How old are the spark plugs?

  • They are at least 2 years old, they look as new, no carbon deposits or oil. I haven´t put a lot of millage on them, I don´t use the car as much. I forgot to say that it gets worst with the A/C on
