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.

Look thereabout, there is a big screw that you turn both ways to adjust the throtlle.
Leading evidence: 'Adjust throtlle' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Adjust throtlle' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt.

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.

As you all know from my previous questions, I am a new 928 porsche owner. That was my dream car ever since I was senior in high school 1987. At that time it was way out of my pocket reach. Well I finally bought one (Guards red\manual\1982). Sometimes I come out with dumb questions because I don't know what is normal. Since I have never driven I dont know what type of performance it should have. I did blow away a M3 the other day though. We were doing over 100 mph on the expressway. I just started moving away from it until I hit 120 mph and he just fated away. Well here is my question. My car has no muffler straight pipe from the cat. I get this strong odor of gas when I press on the gas paddle but the car doesn't smoke at all. Is it because it does't have a muffler or do I have some kind of vaccum leak. The idle is very low it is on the lowest line.
Thank you, for any helpful information

Cast,
As far as your idle speed, it is very easy to adjust it in the 928.. I dont remember exactly, but i am posting a picture with a yellow circle on the engine.. Look thereabout, there is a big screw that you turn both ways to adjust the throtlle. Mine was so low the dash lights would all light again as if the engine stopped, now it is perfect.
As for the exhaust fumes, it is easy. Start the car at cold engine and put your hand on the exhaust to block the gazes running out.. If the noise is still the same (not muffled and deadened) and there is no exhaust pressure that builds up on your hand (let some1 rev the car a bit) then there is surely leak.. Remember the big 4.7liter really breathes!! so your hand should be pushed out by the gazes! I had a lot of problems with the same issue when i removed the cat-pot from under..
Try this as a 'step1' before suspecting Vacum hoses. Do you hear a constant abnormal 'hiss' from around the center console? Are you sure the gazes are not coming out of a bad or torn gear-lever seal (center console in between the front seats)..
Oh! and for an '82 928 to blow away an M3, I am wondering which year the beemer was..
