Default Re: missing/rough running

I'm under a Monday deadline and will probably be working all weekend, so garage time is almost nil. But I was able to test the wires with a better digital meter this afternoon and got some better numbers but still a little high.

1/6 - 27.9
2/3 - 27.7
4/7 - 24.7
5/8 - 22.9

I also pulled the IAC and started pulling wires again. Very little rpm drop when pulling 1-4, noticable chugging when pulling 5-8. Also very intermittent/weak spark on #4 and not much better on 1 & 2. 5-8 look like an arc welder in comparison. Pretty sure at this point I'm pulling the plenum and looking at bad coils.

BTW dielectric grease made no difference, but given the weak spark I'm seeing I wouldn't expect it to.
