yes its non turbo

After chaging injectors to 550cc and installing a aem fic6 and properly calebrating the tps and rpms with fic car does not idle i have to give it gas and hold the acelerator down. no clue if its a egr problem or a lack of knowledge of tunning. casr is a 98 eclispe gs manual.

i was wondering where i can get a copper headgasket for my 1998 eclipse gs 420a and if possible send a specific link or part number.
