When I start driving speedodometer starts bouncing and i lose power. after a few its ok then . now service engine soon light is on ????? help
I start to drive and within 5 minutes my van's speedodometer needle goes to zero then bounces back and forth. I also lose power within this time. Once it is running for a little while, it acts like nothing happened. This started about a week ago and now my service engine light is on .. Any ideas here??? I know I need to get it on a diagnostics test but wanting to see if there are any ideas from anyone. thanks
