Im having a problem with my 2007 Chevy Malibu. It starts fine, idles fine, sounds fine. All spark plugs are firing. I don't have any problem with normal acceleration. Its sudden acceleration that i have a problem with, like when I accelerate to pass someone. Cars rpms will climb but cars speed will not increase. The only code that I get is a P0430 code, catalytic converter is not working effectively. Is this the problem. If this was the problem, wouldnt i have a sluggish car all the time and not just under sudden acceleration. Any information would be helpful. Thanks (This post was edited by Ryis on Jul 27, 2020, 6:06 PM) Hammer Time Ultimate Carjunky / Moderator Jul 27, 2020, 8:06 PM Post #2 of 3 (681 views) Re: Lack of power on sudden acceleration Sign In Yep, sounds like a plugged Cat. You should do some testing to confirm that. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
