what should a map sensor read at idle
i've got a 2000 with cyl 3 , and a cyl 1 misfire. Also runs rough at idle and i get terrible mileage on the highway, i mean like 14mpg. Use to get 19 in my 89. So back to the question , i have a scan tool and the map read 1.27 - to 1.31 inHg @ idle to me that seems wrong, im a mechanic and am only use to maf sensors , so any info will help
