Po303


code po303 refers to cylinder 3--misfire detected===causes --engine mechanical fault---wiring---ignition/ fuel system---injector---ECT/MAF sensor---ECM. check plug and HT lead to no 3 cylinder. Check that the injector to 3 cylinder is operational and not blocking or squirting. Have a compression test done to check for compression / gasket problems

2003 kia Sedona at a cold start the rpm runs very high and it will take over 2 minutes before its slowly starts to drop.


TPS, IAC, EGR, MAF, MAP. all sensors all having to do with the way the car starts and runs. Does it idle fine after warm up or does the idle jump up and down, or does it go so low sometimes, you think it's going to die on you? I'd look at the TPS and IAC 1st. Go to autozone or advanced auto parts and have then plug the OBD II code reader into your ECU and see if they can pull a code.
