Really need some help on this......
Okay, here goes...I have a 1998 Expedition XLT 4x4, 4.6L, air ride suspension w/ 121,000 miles. CE light came on awhile back, had code read and gave #1 misfire. Any helpful advice on changing plugs and wires would be greatly appreciated as I've heard it can be tough. Also, lately, sometimes when driving down highway at about 55-65 mph, the engine seems to just bog down (doesn't lose mph and rpm's don't change...even when pressing acceleretor down further) it just stays at same speed until you release the accelerator for a second or two, then everything is fine for awhile. This is driving me crazy!! I've already changed the fuel filter and run a bottle of seafoam through the tank...no change.
Question 1: Can the acceleration issue be related to the misfire reading?
Question 2: Do I need to use anti-seize on the new plugs?
Question 3: Can anyone provide any further assistance for these problems?
