Hi everyone I have a problem my Dakota time by time stalls but don't shut off it simply lost all his power and don't advance. another issue is that it sometimes gives backfire

 

Kinda like that?

That's a vid I did in June since I was having a backfire.

Does going WOT solve it? It did for me for a little bit but then nothing.

My problem was a bad upstream O2 sensor. Are you getting any misfire codes?

 

Sounds like the O-2 sensor. Min e had same problems.
Mine never threw a code but, while monoring it on a Snap-on
Scanner it showed how lazy the readings were. Replaced it,
All was fine

 

it sometimes trow a CEL light but it like I said is sometimes (Im pretty sure that Daks are temperamental) but yes I've changed the O2 sensors but was with Bosh was imposible to get NGK or anything else for get the truck running on time (lot of work).
It does look like that you are running and then it dont advance lost all the power.
Is it posible that is the catalyser..? well thats the code that it trows and it has the original cats from the 2001

 

I've heard some pretty bad things about the Bosch sensors.

I would've went with OEM.

Does it idle fine? Put your hand by the exhaust pipe and see if you can feel a nice steady flow, if its chugging then there is a chance that your cat is clogged, but you can drill a hole in the bottom to find out for sure.

 

the iddle sometimes is rought but just sometimes also it starts very slowly needs to 2 turns of the key for start in the morning
