You can no longer use a timing light, they are a thing of the pass. You must have an OBDII engine scanner to set the timing on that year engine, because it is now electronic controlled. You will have to hook scanner up to engine and go into the TIMING MODE on the scanner and then move the distributor by hand while watching the scanner to time the engine. THERE'S NO OTHER WAY.
