My vacuum gauge reads about 17psi in the manifold, but when i look on my s300 manager on my laptop the map sensor is reading -27psi. The car doesn't like to run good under heavy throttle and am wondering if the map sensor could be causing this. Anyone have any suggestions?
what map sensor are you using with the s300
i had huge problems using the gm and msd map sensors and when i switched to aem all the problems were solved
im not even sure, it was on the car when i bought it. I looked up the numbers and couldn't find anything. here's a pic with a logo that im not familiar with.
it actually wasn't the map, it was my spark plugs. I knew they were getting old but didn't think they would cause that much trouble. wish i woulda just changed those first! thanks for the help though
