Q: Car dosent not stay on and it's running very rich

asked by on September 29, 2016

Car does not stay on when I turn it over it starts up right away then it dies ( 5speed) but if I hold the gas down at a specific point the car will stay on and the rpms will jump up and down and car will smell very rich the car is OBD0 and car is throwing map sensor code and ignition and fuel system and I'm curious to know if the map sensor can trigger this issue... the car has a map on the throttle body and a spare against the fire wall I tire both but car is doing the same and the odds of them both being bad is kinda hard to belive from my point of view but I would like to know if there is something else I'm missing like is there something else that can cause this situation. Thank you
