Couple 1996 E320 issues.

[Lunagen Labs]

My '96 E320 has developed a couple annoying issues in the last few months.

1. It won't start in park. Well once in a while it will, but 90% of the time, I have to shift into neutral to start it.

2. The throttle is cutting out or dropping at part throttle. It happens right at the throttle position you use to maintain speed in town or on the freeway. Extremely annoying. It literally feels like the throttle blade just slams shut. You have to lift then re-apply the gas to continue. This will happen pretty rapidly, like every 5-10 seconds some times. Oddly, it never does it in the morning, only once everything is heat-soaked by the sun. The throttle servo harness was replaced about 3 1/2 years ago. It was doing pretty much the same thing before that as well. I'm not sure what all was replaced at that time.

If anyone can give me any advice on these issues, I'd be hugely grateful. Other than this, it's driving fantastic, especially for having 284,000 on it
