Re: Odd miss fire at WOT in freezing temps

Alright everyone who is more mechanically skilled then I am (which is probably about everyone haha) The 4runner is still missing at the upper end of 3rd gear and up. I went home last night and checked the distributor's cap which checked out good. I checked the resistance to the pickup coil inside the distributor: good at 150 ohms. I checked the wires: good. I checked the air gap in the distributor which measured 10 thousands: good. I then moved to the ignition coil. This is where I am puzzled. The secondary reading is within spec but for the life of me I cannot get a reading on the primary. Now correct me if I am wrong but the truck wouldn't run if there was a short in the primary, correct? I might have been doing it wrong. I am going to check on my lunch break this afternoon. Any help would be greatly appreciated.
