I jave a 2004 scion xb. Recently my cel came on and my car was randomly misfiring. I've changed tbe coil packs/plugs, checked the pack connectors, 13v steady to each...checked compression, checked valve cover gaskets, and even replaced my ecu. Today I checked my crank sensor for power, and I wasn't getting a reading at the connector. So I left the connector off, and started my car. It started and ran exactly the same as when the sensor is plugged in. This has got to be the issue. Right? Stumped on wbere to go from here. The code popping up was po302, but now its po303. HELP!!
