[QUOTE="David Boer, post: 877734, member: 65415"] Wanted to thank everyone for their comments and suggestions and post the fix for my symptoms in case anyone has these issues in the future and is referencing this info. The IAC was dirty and I used Todd's step-by-step instructions he has listed to remove and clean it. The valve was sticking and the change in weather temperature would make the valve either stick open or closed and the vehicle would not start, just crank. This also explains why the vehicle would start with the pedal depressed (Not throttle by wire) since it would over ride the iac and allow oxygen to enter the engine. Anyway, just used a few q-tips and some rubbing alcohol cleaned it and some motor oil provided lubrication. Thanks again for all the good suggestions. [/QUOTE]
