Hello everyone.
For the last week whenever i make a cold start on my 2000 cat it idles rough for about 5 minutes. During this time sometimes it may shut off and I have to restart it. Reving it doesnt even work cause it just idles even lower and may backfire. Almost doesnt even take the gas pedal at all. Eventually as it gets a bit warmer it idles better although there is a slight vibration. It drives ok when warm but you can still feel the misfire.
I pulled the codes and it gave me 300 301 and 303, so I changed the 1-3-5 coil pack and its still doing the same thing. Any ideas as to what could be causing this?? Thanks
