1999 dodge durango 5.2 205,000 one day it was fine then all of the sudden if u press gas from dead stop it has no power till about 2500 rpm when the cam kicks in. it goes from 0-20 in probably about 3 seconds!! Evewrything else is fine idles perfect NO CODES just did plenum and intake about a month ago. took the CAT off left in o2 sensors. my computer does not have the death flash sticker so thats probably not it. no misfires whatsoever. im totally lost on this one!!! injectors partially clogged???????
If anyone can help you will be my hero THANKS!

 

When was the last time you had yuor tranny serviced and bands adjusted? How's the fluid level?

 

yup +1 on this check the tranny fluid

 

tranny rebuilt a year ago put valvoline atf +4 synthetic in it and also bought brand new torque converter my uncle is a tranny specialist he said its not the tranny

 

If your sure it's not the trans then can you be a little bit (well 2nd grader type) more specific on what the issue is?

 

UPDATED INFO-

problem/issue-is that it has VERY POOR torque from a dead stop, i was in slimy mud and tried powerbraking it and tires would even spin!!! If you hold the brake and put it to the floor the rpm's will go no higher than 1600. My uncle hooked it up to the snap on exodus this morning it has no codes everything seems to be checking fine so my uncle said its probably the torque converter??? does this sound correct? remember no codes came up engine runs PERFECT

 

Any news? Was it the torque converter?

 

Yes it was the torque converter took the tranny out last night and the converter shows signs of extreme heat its was getting really hot!! rebuilding the tranny with shift kit and putting a COAN converter in i will make another post when it is finished
