Thanks CRE
BTW, I did rewire the knock sensor by an import specialist 3 times and he swears the wiring is not the problem. The code 52 doesn't do what it normally would do, for instance the car has power through the entire powerband unless the code 31 comes up then it stalls go and stall again. I had the code 52 on the 7mgte for about 6 months and this doens't seem like a reg. code 52 causing all these problems. I've never had a code 31 and every since the code 31 it's been acting strange and I've yet to see this problem with a code 52. Plus the mech that fixed the knock sensor wiring did it very well with heat shield and extra care b/c I took it too him 3 times to fix the same problem (the code 52.)
