Miss once engine warmed up??

[blknt18]

I checked my icm at AZ and it checked out good. I checked my coil and it showed 7000 ohms at each slot and shoebox said around 8000 or 8500. Idk if that means mine is low or if it is just that...they all read the same though. I also did the icm cooling mod while I had it all apart. I am trying to remove the pass. o2 sensor and having problems... I removed the starter but can't get it past the stock y pipe so I just slide it out of the way but I cant get the the sensor very well because the stupid joint to the manifold is in the way. I kinda get to it but the thing is on so tight. Hopefully I can get it later. I still think it is the opti because wires look great.
