Wifes 99 QX4 was running bad, missing like crazy, tuneup no help, changed distributer runs good, after 2 days I now have a check engine line with the following codes:

PO420PO430PO325

I plan on erasing codes one time and see if it might have been related to the original problem, any suggestions would be great. If exhaust is stopped up can I just put on replacement system with no cats, no inspection where I live!!
