Thread: 05 Grand Prix not starting correctly

i had this problem and so have a few others with 04+ models. i'd recommend cleaning your throttle body. a lot of junk builds up in there . see how that works. you just need basic hand tools to take it off then spray it with tb cleaner. its a good time to clean your maf sensor too. about the windshield washer fluid idk

Had this identical issue on my 04 gtp. Pulled the throttle body off and it was absolutely filthy. World of a difference after cleaning it. Here's a good writeup to follow if you need help: Grand Prixs Of North America • View topic - clean your MAF & Throttle Body
