G6Et Misfire/losing Power

[genx2g]

Hey guys, serious post. my cars been ******* up lately, its a 2008 g6et.

as soon as the car is put under load (usually when boost starts to kick in) it starts to lose power and misfire. I changed the coils today, no such luck... anyone have any ideas or usefull advice on what it is/ what I should do?

Is it tuned?

Hi mate,

Do the cheap/free/easy stuff first to try and solve it;

Are you using the right fuel for the car/tune? (95/98 etc)

Is it old fuel? A bad batch perhaps?

Replace your fuel filter

Put a fuel system cleaner through the car

Check and clean your air intake filter

Coil packs (as done) - are they genuine? Genuine are highly recommended

Fouled spark plugs - Good brand gapped correctly for your application

Boost leaks? Check your piping/clamps/hoses etc

Check turbo for excessive play/bent fins/excessive oil etc

I'd also be checking your drive belts/oil levels and condition/general component inspection

Could be an issue with the Throttle body/TPS?

Hopefully you will have some luck with one of the above.

If it's still horrible, instead of wasting (lots) of money guessing, take it to a reputable shop mate - It'll save you time and money if the cheap/easy options don't work...

Cheers and good luck,

Dan
