Hey guys, i've had intermitant problems with my check engine light coming on:
Code P0108 Manifold Abs pres/Baro press circuit high
It happened while at the dealer and they replaced the MAF sensor on my car, no this code seems to pop up all the time i start my car!! ANy ideas what could be wrong. One thing i noticed is when the service guy replaced the sensor, he never disconnected my battery, because all my radio presents were still intact.
I also have the latest pcm flash, per Dennis' SCT tuner. I get the code with or without the sct tuner also.
Carfixer also gave this info before

2003 VARIOUS VEHICLES - IMPROVED DIAGNOSTICS FOR DTC'S P0107 - P0108
WHEN DIAGNOSING DTC'S P0107 OR P0108 USE THE FOLLOWING: MAP VOLTAGE NECESSARY TO SET A P0107 MUST BE EQUAL TO OR LESS THAN 0.05V. VOLTAGE NECESSARY TO SET A P0108 MUST BE EQUAL TO OR GREATER THAN 4.95V. 1. VERIFY MAP PID VALUES DURING KOEO ARE LESS THAN OR EQUAL TO 0.05V OR GREATER THAN OR EQUAL TO 4.95V. 2. IF THE MAP PID VALUES ARE OK, RE-FLASH PCM WITH THE LATEST CALIBRATION. 3. IF MAP PID VALUE IS BELOW 0.05V OR GREATER THAN 4.95V, TURN KEY OFF AND DISCONNECT ESM CONNECTOR. VISUALLY INSPECT THEN RECONNECT CONNECTOR. REPEAT STEP 1. 4. IF MAP PID VALUES ARE NOT WITHIN SPECIFICATION AFTER PERFORMING STEP 3, PROCEED WITH THE DIAGNOSTICS IN THE PC/ED MANUAL. THIS PROCEDURE WILL BE IN THE PC/ED MAP/ TMAP PINPOINT TEST 'DM' FOR 2004 MODEL YEAR. PINPOINT TEST 'DM' MAY BE USED ON ALL ESM EQUIPPED VEHICLES PRIOR TO THE 2004 MY.
Im going to check the connector myself, making sure everything is up to par with that, anyother ideas? BEfore i have to bring it under the knife again!
