Hi everyone, I have an 05 f150 fx4 5.4 3 valve with 68,000 miles (had it for about 1.5 months) and the past couple days a few weird things have happened when I start my truck. The first is after it cranks over my tach and speedo needles will shake up and down for a couple seconds then go to their normal position. The second is when I start my truck the clock on my radio resets back to 12:00 and it cycles through the CDs in the head unit but keeps my radio station presets. The third is when I'm driving at night now that it is dipping into freezing temperatures my headlights will flick off then back on if I go over a bump in the road. Everything is stock on the truck except that I did the gotts mod. Anyone have any issues like this before? All help would be much appreciated.

 

I would suggest checking the battery terminal first make sure there clean and tight . Battery could be starting to go also . Any auto parts store will check it for free .. When the battery goes bad they go fast .

 

Makes sense I'll check the terminals tonight and I'll run up to advanced or auto zone tomorrow I was going to have my mechanic run my computer too

 

Sounds like a loose or corroded ground...start at the Batt and work you way to the frame. Like Cleveland said could be the Batt going out too.

 

When this happened to me I changed the battery and all was well.

 

Sounds like battery, have it tested. I bought mine at Costco for around $90. Group 65-850 CCAs.

 

Thanks all for the help had my battery changed and all is running good now
