My 323 is has the check engine light on but i do not have a decoder so i need some help...when i start the car it starts but takes a little to get to normal and eventually does and runs well but im selling the car and need to fix the problem.

it kind of just seems like its being starved for a few seconds or something i dont know if it could be the o2 sensor because i just had my m3 midpipe and catback put on. it squeels and shakes for a second then is all good...

can anyone :help?
