I have a bad miss around 90 mph if I'm not giving heavy gas yet it doesn't set off the SES light. This leads me to think it's the ICM because usually they can cause these misfires but won't cause an SES light to come on.

You guys think I'm right? I know it isn't plugs or wires. The plugs have been there MAYBE 6 months and look great. Same with the wires. AND the plugs/wires/coils would DEFINITELY set an SES light.

Any other ideas would be appreciated though if you think I'm wrong!

 

Plugs and wires will rarely set an ses light either. Just pull it off and take it somewhere for them to test. Most auto parts stores can test them.
