Engine Mechanical problem
2000 Dodge Dakota 6 cyl Four Wheel Drive Automatic

I have a 2000 dodge dakota crew cab with a v6.
I have power problem with accelleration and keeping speed on the highway. I will be driving down the highway doing 70 mph and start going up a hill and yhe truck starts loosing speed, I can put the accellerator to the floor and stil continue to loose speed. The only way to start accellerating is for the truck to downshift.

Any help would be greatly appreciated this is very annoying and dangerous.

Hi:
Have you had the computer scanned for codes? If not, I recommend you take it to a nationally recognized auto parts store like Auto Zone. They will scan it for free.

Let me know what they find and we'll go from there.

Hi again:

My mind is more on the map sensor. It adjust timing while driving. I have experienced a similar problem where the map sensor output voltage was normal, would fluctuate within the specs, never set a code, and the vehicle would loose power and at time die.

Do you have a scanner that you can hook up while driving to watch map sensor voltage?

It's a long shot but would be worth a try. Let me know if you need the specs and I'll look them up for you.

If you have the specs that would be great. I check the voltages (with a multimeter) at the connection, at idle and they were at 5v coming from the harness when disconnected and 4.5v when connected. These values are what is spec'd in my book. I will get back to you on the voltages from the scanner when driving.

Thank you
