Buddy of mine has same exact problem cold idles fine after it warms up and drives it when it's idling it knocks but not while driving he has 30k less on his than mine and excessive blow by mine has none told him to get the compression checked

 

I have never done a compression test. I have always wanted to but eiter never have the time or the ambition. Ha. It is just mind bottling how it runs goofy but then sometimes it will run fine

 

What brand of vc gaskets/harnesses did you put in?

 

How many miles on the oil?

 

My gaskets are from accurate diesel. And I just change the oil the other day. There was only about 2800 miles on that oil change. BUT anothe thing, if I turn my TS upto the 100 horse position or the 75, and run it hard down the highway, and come to a stop, the missing and knocking goes away for quite a while but will come back and idle lower and act dumb again. So confused and frustrated..

 

Do you happen to know the brand that they sell?


Have you ever tried it with the chip out?

 

No idea what brand. Just says OEM made in the US for the type or brand I guess. And yes I unplugged the chip from the computer once before but I suppose Since I didn't disconnect the batteries it didn't reset? I'm not sure

 

From what I've read, when the chip is unplugged, the PCM runs stock programming. The chip replaces that stock programming, only when plugged in, with the tunes on it.

 

Just curious as what your fuel pressure is and if you have a gauge what your hpop is running no need to disconnect batteries with the chip just unplug the chip
