P030 (E030) .................................................. . ISC RPM out of range
P034 (E034) ......................................... MAP Sensor Signal Out of Range
P052 (E052) .................................................. ..... PCM Memory Reset
P109 (E109) ....... Keep Alive Memory (KAM) Reset/PCM has lost primary battery power

Last 2 are probably from pulling battery power.

I don't have the codes avail,but was told I needed a MAP sensor. This on my '94 Concours 4.6L Northstar. This will be the 3rd MAP sensor installed in last 50K miles.Currently in shop.Has 87K miles, first sensor replaced at 32K and 2nd at 62K miles. Also had ECM replaced at 66K miles. Help anyone. I have been reading for several days and can't find anything similar. Appreciate help.
