I have a 2005 F150 4.6L. For a couple of weeks I have observed that when I start the engine, all the needles on the dash board flicker/fluctuate at the bottom of the range for 2-3 seconds and come back up to their normal positions. This happens only when I start the engine. Has anyone encountered a similar problem? What is the solution? Thanks.

 

yes, mine is doing that right now…

I was told I needed to replace the battery. I plan on doing that this week and I'll post up if that solved the problem at all.

 

This was happening to me too last night, I took it to the dealer for an oil change and asked them why it was doing that.. They said that the battery was going bad. I had them replace it and it's not doing it anymore!

 

Defiantly change the battery before it dies at the worst possible time for u
