TST(twins version) on my 2005 and P0606 code, rough idle.

[Blacksdieselhp]

I just intstalled the tst with twins program and at idle the truck vibrates pretty bad. The engine doesn't sound any different really, just vibration. It sounds a little different going down the road. the injectors are a little noisy when I sift gears, but that seems normal. TST also says the code is normal. I just want the vibration to stop. Any ideas?

The TST shouldn't be doing anything at idle even with the twins program. Have you tried the bypass plug to see if the TST harness is OK?

Sounds like you have an injector harness or a connection problem.

I got the p0606 with mine when it was first on, but it has since cleared. No idea why you're vibrating, check all the connections and make sure all is well.

Here is my problem. https://www.turbodieselregister.com/forums/showthread.php?t=153371





It is not a common code to show up!! This is exactly why I don't want to call TST about it. They will say "it's common" or "never heard of it" and your still stuck with your problem!
