Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Suggestion
check you coolant level and check your oil for coolant.
Leading evidence: 'Check oil' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check oil' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I took my new (to me) 99 C2 cab (certified) to the dealer last week to address a few things, among them a rattle at idle. The dealership replaced one of the mufflers. I drove the car home to Boston yesterday afternoon, top down (60 degrees out :-), but as I drove for 20 minutes, it started to drizzle, so I pulled over to put the top back up. As the car idled, there was an odor that was reminiscent of burning paper, which I attributed to the new muffler, reasoning that it's fresh metal being heated up for the first time. But when I accelerated hard to get back into the flow of traffic, the car blew a huge white cloud of white smoke. I also noticed some more smoking under hard acceleration (although it's hard to look in the rearview mirror when you are accelerating hard in this car).
Would this smoking be somehow related to the muffler change, or do I have a coolant problem? The car runs strong, temperature seems normal.

Car seemed fine today ... when you have this problem, can it be intermittent? I'm not super concerned because the car is Porsche certified, so if it was a worst-case scenario, I don't mind a new motor ... and the Cayenne loaner they've promised me when my car's in for service -- just in time for winter.

Hmm ... I'll have to check. Didn't look or smell like oil smoke, though ... it was very white. Having owned several oil-cooled 911s, I know what oil smoke looks and smells like ;-)
