Title says it all. My 7 bogs when the throttle is very light, the turbos continue to spool but all there is, is a bumpy ride and puffing out of the exhaust. This problem does not exist at high RPM's/more throttle. Are my plugs bad?

Thanks in advance!

Modifications? What color smoke?

versep

hks rs intake, rb single tip catback, aluminum ast, stock ecu.

i looked out the rear and there was no visible smoke... that could be due to the tinted hatch and the fact that it was pitch black at 3am...

last time the bogging/jerking happened during the day, there was no visible smoke out the back. car idles smooth at 900-1000 warm

it generally happens between 1800~2800rpm, the power really catches me off guard after that.

Are emissions still intact?

versep

Nothing under the hood has been changed since I've bought the car.

0.2821 HC - 0.5 MAX ALLOWABLE - 0.1892 AVRG PASS
0.6169 CO - 9.32 MAX ALLOWABLE - 4.0415 AVRG PASS
0.8586 NOx - 1.24 MAX ALLOWABLE - 0.5280 AVRG PASS
in g/km

Last checked JAN 09
I barely drive her and when I do I go real easy.

Im not sure how I would check the current emissions on my own?

The reason I asked is because what you describe is similar to what is reported by some when the airpump is removed on the stock ECU. At least that's what my first thought was.

TPS adjusted correctly?

The airpump is still in place... its still making that loud noise which I've gotten used to.
Wow thats funny, I was just reading this. I'll have to do this over the weekend.

Hopefully this is the issue, I've also read somewhere hooking up a PFC should solve this problem.

Thanks guys!

Installing an Engine Management System like the PFC won't fix a mechanical problem like a TPS sensor that isn't correctly positioned.

Wherever you heard that from - stop listening.
