She has a Miss

BoeBastang · April 21st, 2010, 01:57 PM

Hey guys, I have a question I need help with. My car has developed a nasty miss. It is an 03 GT 4.6 2v. For about the past month or two my car has been running really rich and at the tailpipe side it sound like it has some nasty cams in it. I had Auto Zone pull my codes and the only one that has came up is O2 sensor which I changed. The code stated "slow responce"... Any ideas?

Could be your spark plugs, or the plugs themselves. Did you do anything that caused it? IE hammering on it real hard?

If you have a miss then it would have read "Cylinder X misfire"... So you don't have a miss

You have brand new o2 sensors in there?

Yes its new and that is the only code it keeps pulling up. I changed the passenger front (before the high flow cat)

You're sure it's pulling the code because of that o2 sensor though? What exactly is the code?
