Default Cold start problem

My 04 GT starts a little rough when it has been sitting overnight. It will turn over strong, but doesn’t fire up for a few seconds, and sometimes seems like it doesn’t fire very strong. Has anyone seen this? I don’t have any mods.

man a 04 and it is having problems already i would say that might be your imagination or you got a lemon. Where are you located? I would say that you might have gotten bad gas. Nothing other then that should be already going wrong in an 04. I would say that you take it to the dealer and have them look at it. That is still in the warranty. Other then that that thing should not be doing anything wrong already.

Thank you, I thought that might be the case. Just annoying I guess... not used to it. Gotta love those quirks.

My car hates cold starts. It's a bitch gettin' her fired up after she sits for a while, especially in really cool weather.

this may sound weird but i got a gel battery but it had 720 cold cranking amps as aposed to the stock 540 and mine starts up in the moring like a champ no matter how cold and i have noticed no other problems with the electricial from the added juice also they hold a charge longer than the stocker

yeah mine does the same thing. it is kind of embarassing sometimes. I only let it crank a few seconds and stop. And if it doesnt fire, the split second I hit the key again it does. [sm=dontgetit.gif]

yeah... when I say cold... I mean not started from the night before. I live in Florida, so real cold temps aren't an issue.

Do you have LT headers? I have had some problems if the car hasnt been started in awhile after I installed LTs. The problem was really bad when I had a bad tune on my chip that was forcing the A/F way to high.

Mine would start, and then misfire if you got into the gas. You had to wait a few seconds before it would warm up and start running good.
