i got a price from toyota and the price was 120 for leads, and $240 for one coil.
coils are known to go in them, so imo, id check the coils for cracks, if theres cracks, it wont boost, the dodgey way of fixin it is by using nail polish sounds gay, but it works
this is my (old) cars engine bay, will the 2nd gen 1GGZE
and the 1st gens have the whole dizzy set up
just thought id host them incase you werent aware of 1gen and 2gen
