Exhaust Converter most likely worn out &
blocked
If the fuel filter has been in there more than
3 years & you have a steel fuel tank,loose
that as well.
Transaxle Modulator won't prevent it from getting
going up to 30 or 40 mph. That you can take out
& test & the hose to it

I have a 99 Dodge Ram 1500 v8 5.9 it's running really bad and when you press on the gas it bogs down and dies out it also rattles and bangs and barely runs


Check for vacuum leaks with a can of carb spray. Replace fuel filter. Check fuel pressure. When was the last tune-up? Plugs and wires.

Occasionally when you first start the car the brake pedal will barely move and it is hard to stop the vehicle when rolling in the driveway, like the power brakes aren't working.


Power brakes are operated by engine vacuum. It sounds like you may have a leak in the power brake vacuum system, so when the engine isn't running, the vacuum leaks away, and you have no "power" in your power brakes. Once the engine is running, the vacuum is built up over several seconds, and you have power for braking again.

I would check the vacuum lines for cracking and the power brake module for vacuum leaks.

No speed when gas pedal is to floor tranny light came on


With the oil light coming on and the brake pedal being hard to press I would say that the engine stopped hence no vacuum -no power assist from the booster.- hard brake pedal. The lock uo feeling may come from the engine seizing up while you were still in gear

Durango starts only when gas pedal is pressed down


Chances are it could be over fueling with an injector stuck open or a vacuum leak from the intake manifold gaskets more than likely

No power on key


There's a gas module located above the spare tire . This is famous for shorting out causing the problems I described and blowing a fuse in the panel, the fuse number is f43 which causes the vehicle to shut down, Hope this helps someone else. Thanks

Could be a transmission issue. Did you hit any objects while driving ? Have you performed a visual inspection under your vehicle ? Have you checked to see if you have any loose vacuum hoses ? Any codes in your engine control module or transmission control module ?
