Well, as the title says.... I've got a skipping 4.6. I bought my 08 about 3 mos ago with 63k. Primary use is towing so it doesn't get used a lot. On my first trip i had a P0307. Seemed to resolve itself. Today at 65k, it sputtered and missed a lot (hotter weather). I can duplicate it. On the highway on-ramp, get up to to about 40 mph, lay back on the pedal so it shifts into 4th or OD (I can't really tell). As it approaches 45 mph or so, with slight pedal, it starts to miss, and skip. If I step on the pedal "noticeably" or floor it, it smooths out fine. No power loss. If I return to just a slight load, it happens again. (TPS?) The problem is, I drive like an old man. I try and conserve fuel, and never give it any more pedal than necessary. This is where the issue happens a lot. I used my Innova 3160 to capture the data 10 frames before and 10 frames during the skips. I just don't know how to interpret it. The dealer gave me SOME info about what THEY did to the car when they took it in in trade. Coils 2&6, and some steering and tire stuff.
Anyone wanna venture a guess on the cause? I wish I knew what to look for with the OBD II. I can get some of the data in graph format, but it's hard to save. I've heard a lot of peoaple on this forum mention about plugs. I do not know the status of them.
I read here that someone paid $70 for 8 plugs. Is that right? Are they special plugs? Seems kind of high. Also, someone mentioned a spark plug "Extractor". Does a normal spark plug socket no longer work?
Any thoughts, suggestions or comments much appreciated.
Thanks.
