ENGINE IDLE, AN CRANKING

2002 Pontiac Grand Am • 157,000 miles

I have a grand am v6, First thing in morning (cold) starts perfect. Everytime after, takes long time to crank, (but cranks). Sitting at idle, doesn't idle well, and sometimes dies. I've changed battery, mass air flow, throrle position sensor, idle air valve control, plugs, wires, KNM air filter. Shitty iudle, please help, point me in another direction.

Yes it's been put on diagnostics, and it (don't remb the code) said ebgine missfire. I've also had my coil packs checked. It's opinion was working properly.

It would really help to have the exact code numbers that would help lead us to the problem. Otherwise we will just have to do a lot of testing of everything.
