Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / January 2007CEL flashing, VSC OFF!!!
Hi, Yesterday I went to Autozone to read codes, and I've got ''the PCM has determined that multiple random misfires have occured in cylinder #2, #3, #4 and Troubleshooting PO300, PO302, PO303, PO304.'' What does that mean? How expensive is to repair them? Just recently I've replaced the 02sensor, the mass air flow meter and the air filter. 1999 LEXUS ES300, 108.000 ml Thank you much! PS My English is not very great, so sorry for my not-very-detailed-message. >Yesterday I went to Autozone to read codes, and I've got ''the PCM has >determined that multiple random misfires have occured in cylinder #2, #3, #4 >and Troubleshooting PO300, PO302, PO303, PO304.'' What does that mean? How >expensive is to repair them? It means just that. A bunch of different cylinders are occasionally misfiring. This would indicate something that is common to all cylinders being the problem. How expensive it is depends on what is causing the problem. Now, what codes are you NOT getting? Sometimes the codes that aren't coming up are as important as those that are. >Just recently I've replaced the 02sensor, the mass air flow meter and the air >filter. Why did you replace these? What led you to think they were problems? I suggest measuring the fuel pressure, looking at the plugs, and checking the timing with a timing light. --scott  Signature"C'est un Nagra.

Why I replaced them, because I had CEL on before. I went to dealership and they suggested to replace them, after what the CEL turned off. But for very short time (1-2 weeks) I have no idea what codes I didn't get. He gave me just 4 receiptes with description. That's all what I have. Thank you for your answer! |
