Random Miss fire/Hesitation
I have a 1995 ford F-250 XL 7.3l that's having an issue I'm having trouble tracking down. It's been doing it for the past 2-3 weeks. Whether I'm driving or just sitting, it will feel like a miss of some sort. It has only died once because of it at idle, but it does it at idle, and under load. While at idle it will just drop in RPM's for a split second like it wants to die, then pick right back up. While under load and driving the whole truck will shake, shut off for literally a split second then go back to being fine. Some days it does it more than others, some time it won't do it for a couple of days. It has happened while it's cold out and while it's warm out.
I replaced the CPS, looking at what else I can do to narrow it down. Not sure if the IPR would affect this, or a clogged fuel filter maybe? I'm changing out my filter regardless soon. It doesn't through any codes, and like I said, it does it some days 4-5 times in a 10 minute period and it drives fine sometimes 3-4 days in a row without doing it.
Looking to see what else ya'll can help me trouble shoot to get this resolved. Also played with the wiring on the VC's and that didn't seem to change anything or replicate the problem.
Thank you for those, in advance, who took the time to read this and give me a suggestion.
