I'v got a 98. 5 24v. Started the truck after work and started fine. Got going down the road and noticed the volt gauge was reading about 8 And the temp gauge hadn't moved. (heater was blowing hot). got home and checked the battery terminals and all was good. Shut truck off for about a minute and started it back up. Fired up without a problem. Both gauges came back to life but now the check engine light came on. Any ideas before I take it to the shop?
