Question about Cars & Trucks
I have been getting OBD Code P0107 which is low barometric pressure in the Intake Manifold. I have replaced the MAP sensor, MAF sensor. I observed the engine bay in total darkness looking for electrical arcs. None seen. I have jiggled the various wiring harnesses and the engine keep running with not a hickup. I have installed a new Coil Pack. No change. I am thinking a flaky fuel pump might be the cause. Too bad I don't have a clear tube in the cockpit so that I can observe fuel flow constantly. I replaced the MAP sensor (again) which sits on the top of the Intake Manifold at the back of the engine. Part# on the MAP sensor was 16212460 with 52171 below that number. I just returned from a 50 mile test drive and to my great surprise, the car is running GREAT, and the shifting is much smoother. It cost me $85.00 at the local Auto Parts store. I am praying that this will fix my problem as it was getting to the point I could not drive the car.
