I have an 05 dodge stratus 2.4L DOHC that makes a rattling noise only when accelerating from a stop, no noise when idling in park or accelerating in park. Check engine light came on a week ago, code PO420 catalyst efficiency below threshold. This is a rebuilt engine from mopar, second one actually, first one the bearings went out after 2000 miles! Is this caused by the catalytic converter going out? It seems to have lost some power, and has just died on me once today, started right up after, and when I got home I had it in park and revved up the engine then let it idle down and it killed, took a couple times to start up but did. Any help would be great, thanks in advance.
have the same problem?
