Message: [QUOTE="Tweeder, post: 1549094, member: 32930"] Decided to bump this thread myself, since I'm still having the issue, and it seems to be getting worse. Tends to be really bad when the air temperature is cold. So, here's new info. Keep in mind I have no codes of any kind at this point. Forscan, AE, Ford IDS, and Snap on Modis all show zero fault codes. Ae, IDS, and Snapon: none show a misfire, all three show all cylinders operating within 3% of each other with contribution/power balance tests; even during the event. Replaced both camshaft position sensor/pigtail, and crankshaft position sensor/pigtail. Took it to a transmission shop thinking maybe torque converter lock up was the issue, nope. Transmission checked out also. All pressures were good, no pieces of anything in the pan, no unusual particles inside, tested all of the valves, everything came back perfect. Changed filters, and did a flush just because they were in there. Did the "bubble test" in the fuel bowl, so I know an injector isn't leaking into the fuel system. Fuel pressure steady at 68/69 even WOT. Boost never fluctuates. RPMs remain steady Speed remains steady MAP and BARO are same koeo, and very close koer. Checked the line from passenger side valve cover to MAP and it's clean and clear. Same with the EBP sensor and tube. I know it's something with the engine, just not sure what. I can hear the engine "pop" out of the exhaust when the event occurs. But the computer won't show me what it is. Any ideas at this point are welcome. Driving me crazy! Again, I have no smoke, and no loss of fluids. Could a bad air temperature reading cause this without showing a code of some kind? [/QUOTE]
