When I did my plugs, I didn't change the coils...Just have them check them while their doing your plugs...If they look worn or torn then purchase a set...

 

interesting enough i got the MAF sensors cleaned today and almost all the stuttering is gone!!! they were barely even that dirty.

regardless denso plugs are on the way.

 

Doesn't sound like you need to go to the expense of changing out the coils then.

 

Hmmm...barely dirty and almost all gone? May not really be a maf issue. The problem will return if it's not. Do have stock plugs? How many miles on them?

 

well basically all the high rev'd stuttering is gone. the only time i am feeling the stuttering now is around 4k'ish. And that is at half throttle.

I have stock plugs, with 26k miles on the car. 5k of which have been modified(tune/exhaust).

 

That's a lot of miles on original plugs. I'm sure if you change them you will see a noticeable difference. Sounds like you pinpointed the problem(s). That's good!

 

I had the same issue , i think i had very bad fuel.
Had to look at it from basic going up .
- first i cleaned my BMC air filter where it wasnt that clean at all .
- Added a bottle of Torco Unleaded Accelerator to new Gas .
Took it to the dealer ship to check my fuel pump and MAF and the problem never showd up .
now am fine and car is running very good , in my case the Fule is the most importent part .

 

1. CHANGE YOUR PLUGS.
2. CHANGE YOUR PLUGS
3. CHANGE YOUR PLUGS
You have more than enough miles on your now-tuned engine to justify the expense. Tuned TTs are far harder on plugs than stock. It is the best $600-800 you can spend on your car right now. Any other issues aside for the moment, just do it. Now.
4. While you're at it, change the coil packs. As with plugs, TTs are also tougher on coil packs. But here's your GREAT BIG BONUS: Changing plugs is costly. Changing coils is costly. If you do the coil packs while the plugs are being done, you will save $500 (YMMV) labor. No brainer. Happy TT. Happy TT owner. Happy Happy Happy.

 

haha i love your enthusiasm!

 

Sam12345 also check your fuel pressure regulator line for connection- see post :

Definately the plugs. Probably don't need coils though. Just gap the plugs lower.

 

similar prob several months ago..... bad coils.... changed plugs and coils at same time...

 

Had similar problem in past... 2 bad coils

 

Plugs and coils. For the plug labor you should go ahead and do the coils. Also 1 range cooler plugs and gap them less. Your factory plugs are around .048 and you should be at about .025 with a good tune.

Good luck...

Another vote for the plugs, change every 15k give or take a few k when tuned. I did the coil packs for the hell of it at 42k but age can effect these vs. mileage it seems with cracking etc. and the added cost is not that bad.
