[QUOTE="sur_real1, post: 16074760, member: 42850"] Do you have anyone in your area with a Ford VCM with IDS? I'd hook that up and do a full network check to see if any sensors are failing or starting to fail. Of note, your handheld tuner cannot perform these deeper checks. Could be a short, failing sensor (maybe crankshaft positioning sensor), or all the way to something mechanical. But if the engine isn't making any new noises like sand in the crank case noise or obvious rod knock, it's probably electrical. With that being said, the very first thing I'd do is get a VCM hooked up and have it test all modules and connections for failures. Then get a borescope and check the cylinders. If all is well there, get a datalog and send it off to your tuner. [/QUOTE]
