Some of these questions were asked and answered on this thread on another site - plug type for AFR's, plug gap, condition of grounds, etc.

pulling wires off and ohm'ing them

old msd wire, one ohmd out at 120ohm then next one i check 1.100k ohm.. that dont sound good right? just pulled a taylor off thats on the car. the coil wire itself is at 1.170k ohm. arnt these supposed to be like 50ohm a foot or so for wires???

ive had it. can an opti actually cause this guys? $300 that im not sure if itll even be a fix bothers me.

perhaps everyones stumbling issues that were opti related really had the same symptoms as mine they just never looked at night? i dont know im spent on this

car has ZERO problems firing up. ZERO problems idling. sounds like it idles like a champ. but you hold the throttle and then you can tell its not fine. stumbling and missing. really figured this would give me hard start problems but it does not.

I second high resistance to ground..check all engine to chassis grounds..one on the coil is not the only one..

pulled off my opti finally. nothing looks bad inside. upon more inspection there is some corrosion forming inside the opti harness itself. now i don't have money for an opti right now so itll be sitting for quite awhile. soon as I get a new harness and opti ill report back and tell you guys whether its opti or not

id check and maybe replace the grounds connections on the coil as well. those terminals can get twisted when you tighten down the bolt and it can pull the wires out of the connector...

also might as well just throw another ground on it.
