Missfire?

[tomp]

Hi, i have a 2000 20vt sport. Recently i have been getting a small jerks from the enging at low revs and in high gear (stops over 3k rpm). I am guessing that the engine is missfiring but i'm not sure. What do you think.

I have searched the forum and it looks like if it is missfiring the it is either a coil pack or the mass air filter. Am i right.

Any thoughts or comments would be greatly appreciated.

I'd imagine coil-pack if it is missing; although i'm suprised you haven't got an emissions light on?

The emission light doesnt always come on unless the coilpack goes completly

It does sound like one is on the way out tho
