Now if the map sensor is bad is there a way to test it or just go out and get a new one? cause when you are driving it it will shut off and stall and sometimes in the morning when you go to start it it wont start it takes a while for it to start! like it will idle up and then down and up and down again and you must shut it off and start it up again! the PO32 code will come up and say current and then sometimes say history? would the map sensor be makeing all these problems possible? and plus its been getting bad gas mileage cause of all this i really need help on this and cant find the answer the check engine like is on and runs fine at times dont know if its map sensor or maybe vacum leak? what can is possile be?
