Re: Bucking/Shuddering F-150
I am replying to my own post but maybe it will help someone in the future. After doing some more trouble shooting and asking more questions I changed the plug wires. That was one of the few normal tune up items i did not perform because the wires looked fairly new and looked ok. A man at a local auto parts shop told me to go home and get it up to running temp. Put the truck in drive with the brake on and give it gas. If it misses and bucks like before it is the wires. Sure enough, as advertised, it missed and bucked around. I changed the wires and haven't had an issue since. Running great. No more engine light and gas mileage has gone way up again. So fairly easy fix for me overall.
