I'm having problems with my 2000 pontiac grand am! It is dying sometimes when idling in park, or while at a stop sign/light and sometimes when i begin to accelerate. The car codes were 0446 and 0452(evap system malfunction and evap system low pressure), so I changed the gas cap because the seal on the old one was dry and cracked. Now the codes are reading 0105 and 0452, if you have any ideas please let me know!

the first code 0105 is the map sensor so check to see if you have a vacuum leak at the sensor or the gasket around it. Maybe even a partial blockage. the other is still the evap acnnister so chec k to see if there is a vacuum leak there or the solenooi d may be bad and stuck open.
