Changed Plugs = Fuel Consumption Increased by 15%... HELP!!!
Hello All,
I've just changed my 04s spark plugs with OEM ones.
Mileage is 20,000 miles.
Fuel consumption has shot up by 15%.
Should i change back to old plugs?
Don't have any Nissan dealerships catering to Zs in the country that i live in.
HELP!!!

Do you notice your engine running rougher than usual?

They're supposed to be good until 105k miles...

Try to do a ecu reset. Look at your exhaust and see if there is alot of black crap. Clean the tips - drive and look agian. If it has a gas smell and alot of black then one of the plugs might be bad or not firing.
