1997 E320, 165,000 miles. This car is new to me. I've noticed a couple very minor issues and have done a search - nothing seems to match up. So here goes.

First of all, acceleration doesn't seem linear when flooring the gas. I don't know what other way to describe it. When accelerating lightly or moderately, everything seems fine. But when flooring the gas, such as when passing or entering an on-ramp, it seems like the rise in engine RPMs just isn't very smooth, almost like it's choking very slightly. And I can never get it quite to redline like with my M103; this one just seems to struggle to get way up there. Air and fuel filters are recent, so I don't suspect them.

The car starts every time, but not always easily. When cold, it starts up almost instantaneously. However, when it's hot, it can take 2 or 3 long (5 seconds or more) cranks to get it going. And I think I can smell gas when this is occuring. Could it be a temp sensor? The Check Engine light is not illuminated, and it runs fine once started, so I'm a bit confused.

Overall it runs great, but I know this isn't how it's supposed to be. And I'm hoping the two issues are related. I'm new to the M104 and have not yet learned all the ins and outs.
