would low vacuum at the map sensor possibly be from a vacuum leak, i checked the line running to the sensor and its perfect. and i can't barly listen for a vacuum leak cuzz my motor barly runs long enough to check

 

A large vacuum leak near the tbi would basically be like opening up the throttle, itll idle real high. Nearer to a runner seems to just knock out a cylinder. Ive left the brake booster line off by accident and the car would still run, just with a dead #8 cylinder.

The high map readings do indicate a problem with either the map sensor, or more likely, an issue that effects vacuum. The egr would be worthwhile checking out. If its somehow stuck open itll cause a really lousy idle. There are lots of other things that can cause the motor to pull low vacuum as well.

The high map readings are more likely indicative of a larger overall problem rather then a vacuum leak.

 

so where would you say i should start at, besides the egr
