My 98' 4.0 drives down the road fine once it clears it's throat but when at idle the exhaust smell is really strong and it stumbles dropping cylinders and sprays a mist of unburnt fuel out the exhaust pipe. Of course mileage has dropped to 9.5mpg.
The O2 sensors are 2.5 years old but only have about 10k of mileage over them. Computer shows a Lean Code for Bank 1 and PO107 Generic (Manifold absolute pressure/ Baro Sensor Low Input)
Any suggestions on where to start?
Here are my numbers using an Innova 3140 scan tool
