Howdy, truck has recently developed a slight romp at idle, doesn't seem to matter if oil is hot or cold, but occasionally it idles smoothly. Truck also feels like it's running on less than 8 cylinder under moderate acceleration, especially in higher gears where you don't have high RPMs to "smooth" out the gaps in power and you can feel it "chugging". Truck is struggles to make 12PSI at WOT in 4th gear (5 speed) at 2500-3000 RPM, and that's with the tow tune engaged on my DP F5 (I know, saving up for a PHP). Downpipes don't look like they're leaking, firewall looks pretty clean. Truck has 162k mi, and I believe the injectors are original. The injectors sounds pretty loud and crackly on the tow tune, it quiets down quite a bit on "stock". I don't recall them being that loud before, but I could be imagining things. Fuel filter is less than 2k mi, oil is 15W-40 Motorcraft with a Motorcraft filter. All 8 buzz fine on a buzz test, and it passes a contribution test. Any ideas? I believe the Baro sensor is no good, as it shows 9.0PSI on ForScan, but from what I read, it shouldn't be causing these symptoms.
