just installed a msd sci+ and bosch coil. now my car really has a hard time idling...

I double checked my wiring... removed iacv and cleaned. readjusted my idle. according to my afc.. its idling from 700 to 760.. but it feels so ruff. i tried changing the plug gap from .28 to .31 still sucks.

when driving, as soon as i hit around 3.5k its stutters... but after that, it feels good. i am running 1 step colder ngk plugs and my wastegate set for 6psi.

im going to wire up the msd box with the stock coil, but if that doesnt work what should i check next? tia

ok i bought a new msd blaster 3 coil, installed it.. still had a ruff azzz idle. after researching i found this site. http://overboost.com/story.asp?id=355

i have the autolite 7mm plug wires from autozone.. i guess i was getting major crossfire. I separated the wires as far as possible and runs like a champ now.

 

autozone is garbage and so is autolite, as well as pepboys. pick up some ngk, or oem. Good call on the coil though
