It all started when i pinned my speedometer. it only goes to 85 on this truck.... i reset the computer but the needles still twitch and freak out when i add electrical load to the truck... headlights, AC, turn signals, electric fan etc. is this a relay/computer issue, or do i just need more juice from a high out put alternator?
