Hi All
I am a relatively new MS3 owner, and quite new to this forum. I have tried searching for a solution to my problem, and although I have some ideas as a result of searches, I really would appreciate other people's opinions on what I am experiencing.
I have a 2008 MS3 with 62,000 miles, a consistent service history and a COBB CAI.
My car seems to hesitate and stutter when I accelerate at low revs. Almost like it wants to run on 3 cylinders, or as if something is restricting the engine (a bit like over-choking?). If I persevere through the hesitation and get north of about 3,500 RPM, things seem to be OK. It sucks for accelerating on the freeway, going from cruising at low revs to try and overtake.
I changed the sparks plugs for Denso iridium ones (as recommended by users here) a few weeks ago and reduced the gap slightly. I have also run a can of Seafoam through the gas tank. Initially I had the 'feel good factor' and thought that the issue was resolved, but in hindsight it is just the same.
I have no check engine lights, fuel economy seems to be normal, and overall acceleration speed is mostly normal. I should also not that when I do accelerate hard, I seem to get an 'engine pushed hard' kind of smell that enters the cabin. This could be completely unrelated. I used to get this kind of smell on my old Audi A3 3.2 Quattro from the exhaust when I pushed the car hard up the mountain to ski resort. I just thought I would add this to build the picture.
It seems from reading around this forum that this could be caused by the EGR valve, but other people seem to get CEL codes when these are malfunctioning.
If anyone has some insight, I really would appreciate it. If you need any more specs about my car, please let me know.
Thanks!

). Is it more likely one than the other? If the cat is dying doesn't it throw a CEL?
) It hit and cracked the driver side front grille/bumper (replacement of that is a different project). After the impact, we ran over it too, so maybe it clawed/scraped/broke something as it hit the front and continued under the car?
) and cleaned the MAFS on that too (that looked even dirtier than the MS3 one!)
