Rough cold idle, almost stalls

[dominicsilvestri]

I have tuned the car up, pulled and checked the injectors, and replaced fuel pump and filter.  What are we overlooking?  The car runs great once it is fully warmed up.  A former Pontiac dealer had the car for over a month and couldn't locate the issue.  I should mention that it has about 54,000 miles on it and had sat for about 15 years.  We also cleaned the fuel tank and have been running Heat and/or injector cleaner in every tank of gas.

are these available somewhere or can I have a muffler shop make one?  Thanks for your reply.

Does anyone have a good crossover pipe available?  I was referred to someone who I contacted about rebuilding mine; however, he has not contacted me back.  Thanks.

I'm the one rebuilding the crossovers. Honestly not sure how I missed your messages, but I sent you a PM. Feel free to email me as well at mshantz83@hotmail.com. I currently have a couple rebuilt crossovers in stock ready to ship.

Thanks!
