There is definitely some slight resistance when starting but it seems flatly distributed over time rather than getting slower or faster as the key is engaged.
I took it to the dealer today because I do not have the time to mess with it right now. They won't even get to look at it until Monday because only 1 person there is qualified to look at it.
I didn't think about trying to pull codes. Oh well.
I did look over the harnesses but didn't notice anything obvious. I suppose they are due for an inspection.
