I have the 2005 limited roadster 3.2L V6 crossfire. I just replaced the serpentine belt and 90% of the fuses in the engine fuse box but, I went to drive it and it starts up fine and runs and drives for about a minute. Then it starts to sputter and my acceleration drops to about 10% of its normal acceleration. It has a full tank of the same 93 premium gas I always put in it. I’m just not sure what/if I need to replace anything?

 

If you have a code reader see if you're getting any codes. Also check all of those fuses and make sure they are in tight. Also, if you have a volt meter, check to make sure the fuses are good. Just because they are new doesn't mean they're good.

 

Thank you. The fuses were checked as I put them in and I tested them again when I got home and they are all still good. I will have to get a code reader tomorrow and will check again and will reply then. I forgot to mention that this same problem happened to me about 6-6 1/2 months ago. When it happened I pulled over turned it off for about 10 minutes and back on and it seemed to fix itself. I should have know it was going to happen again inevitably but I just left that problem in the past. And have had others to fix since then but now this one it top priority lol.

 

Just a suggestion, but to me it sounds like the throttle body. I had the same symptoms on a Saturn outlook with a bad throttle body. See what the codes tell you first before replacing anything.

I have the same issue I am troubleshooting now, although my car has been sitting for 6+ years. I haven't had a chance to put a code reader on it yet, but if no codes going to start with the fuel filter in my situation and work from there.
How long since your fuel filter was changed?

 

Part of the problem is sitting for 6+ years. How old is the gas?

 

Oh entire fuel system has been drained and flushed along with new fuel pump and filter and refueled with ethanol free fuel. I didn't drop the tank and wash though as fuel ran clear of debris as I was draining it. Was more offering a thought on other options if it isn't throwing codes for the OP.
