Welcome to the group!
... Some of the Frontiers come with special spark plugs that will last well over 100,000 miles. But when certain sensors that control the computer get dirty (or bad gasoline) the engine, injectors and plugs can get carbon deposits.
... My ‘99 3.3 V-6 developed a high RPM miss and low fuel mileage at 30,000 miles. I used Lucas fuel treatment and it helped. The 10% Ethanol that is added to gasoline in most areas is slowly damaging fuel system parts including the fuel injectors. Also, It’s not a bad idea to change the transmission oil every 30,000 miles. See if you can find an owners manual for your truck.
Have a good one.. Don S..
