At first my fuel pump wasnt prime when i turned the key, got a new main relay problem fixed and now when i drive it sputter and pops when at normal engine operating temp from like 2 1/2 - 4k rpm ..... but if i floor it ,its like goes back to normal. Idles good when cold but low and a little rough when cold ..... what do you guys think it could be

Carbon deposits in the EGR valve can cause it to stick open a bit and cause a rough idle. If it is bad enough, the engine will stall out when you slow to a stop

1st check ur timing..make sure its top dead center when u do it. after that check your dizzy, if that fails then it may be the injectors or faulty map sensor
