Went to drive the car yesterday and the car starts running like crap. the map was reading 45 psi at idle and then after tinkering, it would only read 0-2 psi at idle. I get voltage to the the plug, and based off my vacuum gauge i dont have a leak. Build is fresh and the computer has the correct map setting installed and programmed. Trying to figure out how i can see if its the voltage from the ecu to the map, or if its the map itself. I don't have a map laying around, i ordered one but its a week out due to me being in Germany.

Disconnect the MAP, then check what voltage is read on the output wire. If a power or ground wire is rubbing on a broken MAP output wire, it will not care what the MAP is saying. You can also slap in a stock MAP and see if it does the same thing. Considering it was reading full voltage and now it's reading 0-2psi at idle, chances are the sensor is bad.

found a stock one here from a guy for 5 euro. Shit works now. Will go and do some street cruising tuning and my 4 bar should be here later this week.
