I'm new here but have been browsing around the site with no solution. Earlier today I noticed I had slow/poor acceleration on my truck until I get to about 28-32mph, but it only happens when my truck is warm/hot about 185-200. I've already checked what I could and what I have found here but no success.
I also looked at what has been done differently in the past few days; which was getting wash (not under hood), and filled gas)
I'm driving a 97 ram 1500 V6 3.9L.
Any help is greatly appreciated

 

Manual or automatic?

 

Hhmmmm, probably about the time it's going into closed loop.
Checked your O2 sensors.
Maybe a plugged cat.
How's your plenum?

 

Automatic

 

as far as I know plenum is good. And I just tried freeing up cat, it helped a little.
Listening and looking closer it feels like it's not shifting down from 3rd, which confuses me as just less than 12 hours before this problem everything was doing perfect.

 

Check the TV cable, make sure it is adjusted properly, and actually working.

 

Didnt think of checking there. I'll go ahead and do that later.

 

Ha, welcome to the club! I have the deathflash so I have great power when cold but as soon as temp gets to 170 it's like I hooked up a trailer. Dead dog!

But in your case, probably what these guys said. I know nothing about magic slush boxes.
