Question

• changed spark plugs now runs horrible also had a leak in the coolant. Now barely starts and shows check engine light

Answer 1

Hi there,

This code is for the engine coolant temp sensor. It can cause some running problems if it's failed because the computer will make the wrong fuel mixture based on the temp of the engine. Also, check the plug wires and firing order. This can cause terrible running issues.
