My 2005 Ultra has been at the dealer for several weeks with incremental things being done to try and fix this problem. A/C changed, new battery, temperature sensors, re-mapped and dyno'd, stater... Still having same symptoms: It turns over but won't "catch" or start unless I crank on throttle -- then it fires up. If I don't crank on the throttle, it turns over and no start. It'll do this cold or warm. Any thoughts? Very frustrating...and getting expensive.

Thanks in advance.
