I have a 2003 Ford Taurus station wagon. The check engine is on and I have the following trouble codes P0705, P0122,P1121.P1120. What do I need to do to get this car repaired?
When driving the car shakes and the check engine light flashes. What could it be?
Anytime the check engine light flashes the engine should be turned off and repaired before permanent damage is done. The most likely cause for this problem would be an engine misfire. You will want to start by have the engine codes pulled with a scan tool. This process is generally referred to as computer diagnostics.
