Car stuck in limp mode after replacing thermostat

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. You state the "code was the thermostat". Exactly what code was it? No code indicates failure off any specific component. It states what was measured and in what area. Then testing must be performed to drill down and find out what is happening. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
