Yesterday I just cured my bro-in-law's '98 Lancer.
It was having a bumpy idle and hesitation on acceleration.
Check the plugs//cable and found one of the cables (with a built-in coil) faulty.
The part cost a whopping $95 for one cable with built-in coil (there are 2 in the car - it's a 4-cyl). If a complete set had been bought, it would have cost us $190 (for the two cables with built-in coils) + $42 (for the other 2 cables) = $232!!!
My set of Beru cables just cost me $48 for my Babybenz!!!
Hehe...
Good luck, dude.
