Well what do you mean "tune up"

If you changed the plugs,make sure you have the wires right

coils Engine
L1/L2 L1/L2
T1/T2 T1/T2

biggest easiest mistake.

easiest to fix..

follow the wires from coils,it will say either T1/T2/L1/L2

The rotor housing towards the front of the car is 1
The rotor housing to the back of the car is 2

T means trailing,also easiest way to remember is t stands for Top
L means leading,which can easly mean lower..

Match the wires from the coil
L1

would mean rotor housing 1,Leading (lower)
