Check the fuel pressure

Check fuel filter it might need replacing, then have fuel pump checked.

replace your fuel filter....i had a monte carlo that did the exact same thing....ran great untill i jumped on the hwy with it....come to find out it sat up for a while and rust and crud developed in the gas tank...i should of droped the tank to clean it but i chose to replace the fuel filter every month.....plus its the easiest and cheapest thing to start with....it just seems like if it was your timing it wouldnt run right at all and a fuel pump is usually a part that works or it doesnt work, and if it doesnt work, well, your not gonna go anywhere then.....good luck with it

Check the catalytic converter. As the engine heats it up the gunk expands which will cause the problems you are explaining.

Did you ever find out what was causing this? I am having the same problem.

Sounds like an EGR valve sticking. Start the engine cold and let it warm up. As soon as it starts to hesitate/stumble, pull the vacuum hose off the EGR and if the engine maintains a steady idle, replace the EGR valve. The EGR is sticking intermittently but it won't be long before it sticks all the time and you won't be able to keep the car running when it gets warm. This is an easy diagnosis, removal and replacement for the do it yourself car owners. Please rate me on my answer.

If i rememeber correctly these cars have 2 coil packs. Check the coil packs on this car..

hi I had the same problem i did what you but i did not change the spark cable or caps if you change them you sould get rid of your problem until your next tune-up.
good luck.

sounds like the coil pack is the primary suspect here ..especially if your miss is migrating to cylinder#2 now....other issue possible...do a compression test...head gasket failure losing compression between #1 and #2 ....also..and specifically for *other user* comment... check function of EGR valve for vacuum leak into intake causing stumble misfire shudder and engine dying issues
