so my truck if it sits for a day will run really rough for 10-20 seconds before smoothing out, it has gotten progressively worse... If I go to the grocery store or something where its been sitting for less than 5 or 6 hours before restarting it starts fine, but if it sits all day or overnight it starts rough again.
also occasionally driving down the road it will start to miss for a few seconds then smooth out, its an auto and I shifted gears and it continued to do it, I also tried flooring it and it continued to miss for the few seconds. I am not getting any CEL codes. I have cleaned the IAC and MAF the coil pack only has about 10k on it, same with the plugs and about 20k on motorcraft plug wires, where do I go from here? its a 99 4.0 ohv with 130k on it.
