New to site ... Found an old thread via google about the "infamous camshaft position sensor" and it helped me a lot! Thanks!!! I have a 05 Mustang GT - got a code for camshaft position sensor (340) - changed it out - cleared engine code - code came right back when I jumped on highway next day. Went and tested my battery and alternator. Battery good, alternator bad. Replaced alternator and code cleared on it's own, car is no longer "bucking". Now ... I'm having another issue since I switched out alternator two days ago ... hoping y'all may have some advice.
When I don't have clutch pushed in and/or I'm out of gear, my car drops down to like 300-400 rpms ... feels like it's going to stall on me but doesn't. If I'm just sitting, idling, the rpms will recover quickly and shoot up to around 900-1000. I've never had an issue like this. No engine codes and car is running great except when I come to a stop and then my rpms just drop quickly to 400ish and it acts like it's about to stall. Also my AC will go from blowing nice and cool to warm. Really strange. Any ideas?
