What is your question?
The only noise I hear is when it backfires
What makes this problem better or worse?
Doesn't matter
How long has your 2003 INFINITI FX45 had this problem?
A year but I don't drive car that often

Backfiring is due to crankcase ventilation concerns, air intake restriction, or exhaust restriction issues typically. Hands on diagnostic testing is required. www.repairpal/com/repair-shops
