I have went with an MSD SS external coil,cap, 9mm wires and NGK platinum plugs and it still missing a little a little. I actually can feel it more now. The engine bogs down alittle when give it throttle at first. I had a newer JDM F22A1 put in about 9 months ago. The guy that did the swap put my old intake, injectors and distributor on the newer engine. It had the slight miss before and still does. I do not want to continue to buy parts without knowing what is really wrong.

I'd really appreciate any good advice.

Injectors are way too big for a stock motor.

What is your A/F ratio with the stock injectors ...... sounds like you're rich causing a choke condition ...... bigger injectors will make this worse and to go that big, you need E-manage to change the duration of the injector pulse.

Also, I think platinums are ok with the MSD, but I know that capacitive discharge systems burn the sharpened tips off of iridium plugs. Might be something to check.
