    I have a 05 wrangler 4.0. Newest issue is a misfire code. P0305 p2096 p2098. I changed coil. Nothing. Changed #5 injector. Nothing. Still missing like a dead cylinder. Prior to this I’ve been battling lean codes on all o2. I have changed them all.

    5.7 V8 with Whipple Supercharger, TH350 w/B&M Shifter, NP205 TC, Dana 60 front 4.56, GM 14 bolt 10.5 rear 4.56, 4 wheel discs, Bilstein shocks, 6" lift on 37's, Autometer gauges, all led lighting and a few other things.
    I'd check cylinder compression to see if #5 is low and do a vacuum leak down test. Sounds like you've already changed all the likely suspects.
