2008 Tl-S 6MT

Cars been acting up lately.
1)Bogs between 2000-4500rpm
2)When i get to a stop, Revs drop to 500rpm then bounce back to 800rpm

I Decided to take it to Acura and get some info as to whats going on as i dont have a CEL showing.

Just got a call... Sir all cylinders seem to be miss firing we dont have more details but our Mechanic would like to keep the car over night in order to do more tests in the morning.

The guy had no Details to tell me other then miss firing. Not sure what could have caused this, if anyone has any ideas please let me know.

it can be the fuel injectors or the egr valve ports are clogged

This happened the first year I had my then brand new CL-S6. There was a TSB on the coil packs. Indeed this was what the problem was. While they we're changing the coils, Acura Techs changed the spark plugs too. So have those two things checked out I'd say. I'd bet your issues will be this. Stock the 6speed used NGK Iridium Spark Plugs. I wonder Which plugs the 3rd/4th Gen TL's use.

Found out it was a vacuum leak. Car is running much better but still not 100%.

They told me it has symptoms of car that has had many miss shifts. (I haven't miss shifted my car in the time ive owned it)

Unfortunately they cannot describe these symptoms to me and i have never driven another TL-S to know the difference... so i dont know where to go from here.
