It's usually recommended every 50 to 60 thousand miles.
dude you need a tune up
Spark plugs need to be changed. had the same problem and it disappeared when I replaced the plugs.
I just spoke with a Parts person at a local Toyota dealer. He told me that the 2004 Toyota Matrix requires Iridium spark plugs, which retails for about $12 at the dealership, and it should not need to be changed until 120,000 miles.
I would replace the spark plugs after 50K, the wires and plugs again at 100K.
The spark plugs on a Volvo S70 T5 should typically be changed every 30,000 to 60,000 miles, depending on driving conditions and the type of spark plugs used. It's best to consult the owner’s manual for specific recommendations based on the model year and any updates. Regular maintenance checks can help determine if they need to be replaced sooner.
Use a gap-less plug. That's is, one that doesn't need to be gapped. Such as bosch platinum.
platinum plugs 75,000 miles. resistor plugs 30,000.
