The car did have some problem, mainly with the timing which i told them to redo when i dropped it off. So it was no shock... There were other small problems that had nothing to do with it knocking in the first place, im sure all that was causing knock was ecu in the first place but i am glad they found other problems and fixed them. One problem they found was that my tranny was grinding very badly, i had no clue it was doing this so they changed my tranny oil to help the problem out somewhat. So when i pick up the car it was grinding pretty badly so im like wtf its never done this before so i pull over and first thing i see is the 3in IC piping is hitting the shifter linkage. I was just thinking to myself "a shop full of guys who do this all the time couldent figure out a common problem like that?" Anyways that was a good charge that was needless. Also the reason i didnt leave the palm with it was because it would have been dead by the time i picked it up and i dont have a card to save MMCD on so it would have been erased...
Here are some threads 3sx should have read before changing out the fluid...
