Already replaced the MAP sensor, cleaned the connector and erased the codes. My CEL light keeps coming on about once a week with the same trouble code,usually I reset the comp. and it is OK for a few days. Last time the CEL light came on the car started jerking I thought it will just die on me but managed to get home and by unplugging the Ignition control module and cleaning the connector and resetting the comp. it is running fine now.Then I checked the MAP sensor harness (engine off switch in on) and seems to have no voltage where it is supposed to have .5 volts so I´m afraid the problem will come back! Any advice be appreciated.

Ok today the CEL came on again and after two or three times that I had to put the engine off, it turned off by itself.
I decided to check the MAP sensor wiring and disarmed the monster connector, now here is what I found so far the two pins at the side of the MAP sensor connector show continuity to the monster connector but the one in the middle does not, anyone knows if that wire goes to someplace else???? I suspect it may be damaged but not sure till I can check for continuity.
