Map Sensor

If The Map Sensor Is Unplugged On Car Will That Make Any Difference? Mine Is Unplugged And Has Been For Years, And When I Plugged It In Car Seems Not Run As Well As Unplugged.

In a stock type setup, the MAP only drives the LED boost gauge. There is no ECM inputs that it needs.

It can cause a vacuum leak though. So I would at least make sure the vacuum hard line is either connected or caped.

I Only Have A Chip And Catback Exhaust, And Vacum Line Is Plugged Into Sensor Just The Electrical Connector Is Unplugged And I Have Autometer Boost Gauge, So If Chip And Exhaust Doenst Make A Difference So Be It. Thank You
