svigarfarms Posted October 17, 2017 Share Posted October 17, 2017 Getting in accurate reading on the temp gauge , some times it will move as the turn signals flash.

svigarfarms Posted October 18, 2017 Author Share Posted October 18, 2017 Anyone want to point me to every ground on this thing. I just bought it had a 96 before an right now wish I had never seen this one ran a load today I still think I'm getting inaccurate reading on the temp gauge an fuel gauge. Cleaned the plug behind the dash on the left side. Seems to have stopped a lot of it. It's got the 355-380 engine in it the old 400 would run circles around it I believe. I stopped at mack he hooked the laptop to it an read the ecm temp sensor an at the time the one in the dash was not even close. If I understand him right he set it to shut down if it gets a hot reading on that one???? By the way the guys at vo mac in new haven Indiana were very helpful.
