Ok I have a 1995 neon on any day it will start and idle fine I drive 20 mins to work every morning and it runs fine and have never had any issue at night but on hot days like 80 degree plus days if I try to make that same trip home and back it will start to cut out and then soon after die but while its cutting out if I barely press on the gas peddle it will slowly accelerate but if I put the peddle to the floor it pop and will just come to a stop one it will no longer run or start I let it sit for like 20 mins to an hour it will start and run fine but not for long if I let it sit long enough for the temp gauge to go all the way down it runs as if nothing was ever wrong I put a new ignition coil on today and after I put it on I started the car and it started missing as soon as I tried to give it an gas I put the old one back on and it throttles up just fine re hooked up new one and it wouldn't even start please help me

Random misfires are hard to diagnose and should be left to pros. Do what I've said in replies

Do it with engine running if it will start otherwise looks like you need a fuel pump

I did the test with it running it said 0psi but I drive the car everyday it only starts acting up once u drive it for awhile when its hot out it has never done it at night either it just starts to sputter when u give it gas and then it eventually just stalls and won't start until it sits for a little bit the runs fine for a little while then it starts all over till it quits again

Have alocal pro look at this I think you have a fuel pump problem causing a couple of the codes. For idle air try cleaning iac hole and throttle plate on both sides with choke cleaner. I have no other suggestions or comments for you.
