My 2001 Accent (5spd, 80k kms) started showing the service engine soon light the other day and upon checking the codes, has a P0442 and a P1128. P0442 says an evaporative emission System leak (small) but I'm wondering what the P1128 is. Any ideas as to what this code is and what it may mean for me to check? Seems to hesitate when the engine is cold, almost like it's misfiring until it warms up. Would a bad gas cap possibly cause this?
Thanks
