Hi, just joined the forum!
I am having some issues with my 2004 Volvo s60 2.5t;
I recently got the codes read at autozone and it said I have a all 5 coils failing and my Fuel Tank Pressure Sensor is also failing.

I have no been able to find the Fuel Tank Pressure Sensor, only the Furl Rail Pressure sensor which I have changed within the past year (also failed out).
Any ideas what this is or where to get a replacement.
I have seen some used ones on eBay, but I was hoping to get a new one if possible. I have not contacted the dealer yet, as I wanted to come here first.

As for the Ignition Coils, within the past 8 months, I replaced all 5 with very inexpensive ones. It drove fine for a while and now it is saying all 5 are failing again.
Is it a bad idea to get no-name ignition coils?
If so, which ones should I get?
Are the NKG ones okay?

I am also going to be swapping the spark plugs soon- I have always used Iridium plugs, but wasn't sure if I should stick to those or use Double Platinum, Ruthenium, etc.

Thanks for any information or help!
