Thank you.

I have heard that the TSRM has the wrong torque specs on the engine in most cases, like for example it says to torque the head down to 58ft/Ibs when in reality it should be around 75-80ft/Ibs. I have heard of some other ppl torquing it to 90ft/Ibs. So it's possible that something might have come loose and that's why you have a knock...Also, you should have 1 knock sensor for a 7MGE, and 2 for the 7MGTE these knock sensors will read engine knock in the cylinders and if one goes off you will get an engine light come on. Have you done any upgrades to the engine? Is it Turbo or NA?
