Hello All. I have a 1988 Olds Cutlass Ciera with a 2.8L. My dad and I need to change the MAP Sensor out. Does anyone know how hard/easy this? Also, the reason we are doing this is because sometimes on cold starts it won't run unless you pump the gas. It does it while running but will clear up when you get the revs up. It only does it for about 1 min. and then its fine. Will the MAP sensor fix the problem? We are 99% sure it will, so is the mechanic at my work, but is there anything else that could cause this problem? Thanks in advance.
