    2000 STS Replaced MAP Sensor & MAF now NO Power

    I recently had issues with my 2000 STS and the codes were telling me bad MAP Sensor so I replaced it, after the replacement another Code kicks out MAF Sensor so I replaced it, Now when I step on the Gas Car does not move forward with effort power. What could the new problem be?

    I'll bet the MAF clamps, rubber connector rings, and/or the intake duct and resonator are cracked or improperly installed. ANY air leak at or after the MAF will set all sorts of odd mixture/airflow codes.

    Click on my username ^^^, open my profile. two picture albums, 6 pages of pictures and diagrams - many of our intake systems and sensors

    Check for Vac leaks. My intake bolts were looser than hand tight....
