[QUOTE="machoheadgames, post: 440022, member: 18789"] I think by setting the crank to 8° and then stabbing the distributor, you are basically setting the distributor rotor off by a tooth on the cam gear. I’m surprised that ran well. I also have never heard of anyone doing this on a YJ or TJ 4.0, so I’m surprised this dude recommends it. Not doubting him, I just find it interesting. Downs makes a good point about the TPS. Those can cause all sorts of wonky conditions. Might be worth testing that first before buying a coil or TPS or anything else. Either of those can make the driving experience very poor, but at least the TPS can easily be tested. [/QUOTE]
