Hello i am having a problem with power loss when the truck is up to temp and if you turn it off for just a few min and start her back up it will be very sulggsh, lazy ,numb. some times not as bad as others. heres what i have replaced pulgs when i got the truck 200k (km),tps,iat, the iat helped a little bit . its a 2000 3.9 5speed 239,000km. thank you for any info

 

Could be your o2 sensor. The ecm doesn't read them untill engine temp has reached opetating temp.

 

That is what i was thinking. thank you.
