Multiple miss fires
I have spent alot of time looking through threads about v10's miss firing and have not been able to resolve my issue. I recently purchased a 2000 v10 f250 with about 220000 miles on it I bought it knowing it had one miss fire but now I have a total of three. Te truck has no problems accelerating but at a little over 40 mph the engine shakes quite noticibly and after 60 i5 seems to smooth out. After alot of reading I replaced all of my plugs and ignition coils, ran a can of sea foam through my gas tank and my intake with no change to the miss fires. I have started my trials with the fuel injectors by switching them from miss firing cylinders to ones that aren't. Some other information is my truck has no egr on my intake.
Any ideas or extra information would be very helpful and greatly appreciated.

I agree with redford. Check for vacuum leaks. A common problem with the v10's is the elbow under the throttlebody to the pcv hose. I switched mine and helped clear a random misfire code. GL

I will check on that today thanks alot.I have already replaced my pcv valve and noticed when running the vacuum hose from the pcv valve to the throttle body is compressed there is suction but I was just wondering if that is normal.

I had no luck with finding any vacuum leaks I replaced the tubing running from the pcv to the lower throttle body and it seems to run a little better. But I still have the miss fires they are on culylinders two, three, and seven.
