It could be a bad connection sure.You should have 5 volts on one wire,ground on another and the middle one is signal return.Have you made sure that you have vacuum to the map sensor?

Reply to Davo/diablo666's Post: No I ahve not checked the vaccumm in either of the m.a.p. sensors I have replaced the car hasd been sitting up for a couple years before I purchased it and it has some electrical problems such as the dash cluster display and the fan , etc so I decided after I replaced it to check for a electrical connection after the service light went out when I first replce it replaced it but when checking the code again it srill registered m.a.p. sensor and now it runs really bad and I also changed the spark plugs and wires
