Question about 2000 Dodge Durango

My 2000 dodge durango 4.7 has started to use alot of fuel. It surges when driving on the road. Codes have said that bank 1 and 2 are burning to lean. Also at startup black smoke comes out the tail pipe. Both 02 sensors were just replaced.

It sounds like you have a vacuum leak or a mass air flow sensor that is dirty... i would be inclined to check the mass air flow sensor for being dirty as it seems to actually be running very rich.

2000 lincoln navigator unable to bleed up fuel


I think I would try the easiest thing to fix and then see how much straightened out. The fuel tank vacuum will probably be a gas cap not on tight or defective or a gas vapor line has a hole in it. You may need a smoker to find that leak if the gascap is okay,

Bank 1 should have cylinders 1,2,3,4. Since 3 cylinders that are in the same bank are misfiring it must be lack of fuel or bad spark. The tester said that bank was lean. If the plugs were not firing it would be rich with unburned fuel. The tester also indicated the other fuel tank vacuum bleed problem.

You might try the power connector for the Bank 1 injectors or check the injector wiring for #2,3,and 4 to see if they are getting power.

Remember to clear the diagnostic meter to see if the trouble codes return. Would be interested in the outcome.

Codes


Your sensors are reading correctly so leave them alone. What you have is a fuel delivery issue. Your MAF sensor is telling your engine to lean your fuel mixture. You need to remove and clean or replace (is better) the MAF. But first replace your PVC valve and clean your ERG valve.

2000 dodge durango 5.9 surges and stalls at all stop lights.


first check all vacuum lines especially the one behind the throttle body to make sure none of them are off also have it tested to see if one of the coil packs on the spark plugs is bad and it hasn't had a tune up in awhile now is a good time to do so fuel filter plugs coil pack on the plugs if needed and the drive belt checked
