Well I'm trying to track down a sporadic miss. At idle and low load. Looking at injectors first. Everything ignition wise is all fairly new minus the opti. Just wanted yo see what people thought of the reliability of the msd unit if I do end up having to replace it. Car has 130k with original opti

Mine had 140k before I replaced mine I was hunting a miss also turns out I had 3 cracked spark plugs you may want to pull those and check them as wires before you jump to the opti

As 96z28SideSwype said, AC Delco or Delphi are the most reliable units from what I've heard. Delphi should be cheaper than AC Delco.

I'll check them again. Plugs are maybe 8months old wires are 4 months old, coil and ignition module 1 yr old. Been doing this for a bit now, looking at a job where I will be commuting 45 min each way so just doing any preventative maintenance I can

I had a miss under load in any gear under 2k rpm after that it ran like a champ. Have you don't any aftermarket mods since you checked the plugs and wires last?
