So the explorer developed some sort of misfiring/sputter/stuttering last night. Occurred on the highway while cruising and was pretty bad. I had to keep gassing then letting go, gassing then letting go.
This morning before work, the explorer had a constant light sputter and developed a more profound one while cruising and even accelerating. If the sputter got real bad, I could smell what smelled like weed eater gas inside the cabin. As you could also imagine, there is a loss of power. Upon googling and past knowledge I have came up with the following conclusion. Can someone help me confirm as to which is true? I can’t just throw money at a problem like I used to so I want to pinpoint it.
1)Engine is misfiring due to potential dying plug. Records show in July of ’08 I installed Champion Copper Plus plugs due to a HHO project I was doing (never completed). I read copper plugs need to be replaced once a year or 6k miles. Replace with Autolite Double Plats?
2)IAC is sticking. The stock has been replaced about 50k miles but I know the IAC in these trucks can be problematic when they get real dirty. Change it?
In the past I’ve had this problem but only once in a blue moon at a stop light. The truck would idle funny so I would put in N, rev her a bit, and the idle would return to normal. In an attempt to fix this, I replaced the EGR valve and EGR Valve position sensor but it didn’t work.
