    2013 Wrangler stalls at traffic lights but only when ac is running. Dealer replacing a crankshaft sensor. Any thoughts? TY

    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.
    Faulty CPS usually sets an engine code (check engine light), rough idle, stalling, hard start. Doesn't fix itself and run fine when you turn the AC off. Dealership may have scan info or other reason to believe the CPS needs replaced.
    Make sure that your AC compressor isn't cycling because it's low on Freon. Short cycling screws with the signal to make IAC increase idle when the AC compressor kicks in.
    Keep us posted if you find solution.
