Crankshaft position sensor not properly set???

02 auto TJ 4.0 Long story short, my CPS failed me last July and I bought an aftermarket one. Since then I will get misfire and lag at random times, usually at 2800+rpms or hill inclines. I did some research and found that aftermarket CPS can cause this so I went to the dealer and got a MOPAR one. Well when I went to pull the old one out I noticed the little paper spacer was still on it, you know the ones that's supposed to get sheared off after first startup... Anyways, I installed the new one and first start this morning I took a lot of cranks to start, I'm wondering if it isn't set properly, anyone else have this problem? How do I go about adjusting it, not much room to work with.. Thanks

I'm not sure if they are adjustable, but I just read another thread about making sure is pushed in all the way. The paper spacer should be sheared off and I guess this sets the proper gap.
