help! truck running wrong
 
The past few days when I head out for the morning about 10min into driving my 3.9 just bogs down and acts as if it has no power even when I nail it will just sputter and buck and sometimes back fire. After like 10 min of feathering and revving its fine. WhatsWhat's wrong?!

Sounds like you've got a sensor on the fritz. Question is, which one. I'd pull the AIT and clean it real well, see if that fixes it. A can of Seafoam in the tank and through the brake booster hose wouldn't hurt either. The Seafoam will clean some of that crap out.

Dougie91 08-20-2013 07:24 PM

I have put seafoam in the tank already but not the brake booster. and what is the AIT? also I do have a bad o2 sensor, its the one after the cat though, people have said that wont affect the truck, this true?

The AIT is the sensor that takes the temperature of the air going in to your throttle body. The computer leans or enriches the gas according to the temp.

A bad 2nd bank (aft) 02 sensor will affect it. You should change, or have it changed, out.

alrighty, so I did the 02 sensor. engine light is gone. I still have a little of the bogging. it like falls on its face in 2nd

When's the last time you had the tranny serviced?

Dougie91 08-27-2013 07:49 PM

you mean like clutch and flywheel? i was told the fluid in a standard tranny should outlive the life of the tranny

DOH! Didn't know it was a standard shift. So it's prolly not the tranny. Not really sure, now. Hopefully another member can chime in with some ideas.

I mean its not really dying, just seems like its not letting out all 175hp of fury haha

I had an 89 Dakota with that engine and tranny, and although it was lighter than the Ram, I still wasn't impressed with the get up and go.
