Engine knock 3k RPM

Supra Saiyan · 02-17-2011, 08:27 AM

I have some engine knock at 3k RPM - 5k RPM...
(Tap tap tap tap tap sound, or you could say slap slap slap both accurate)

Things I did recently to my 7MGTE Supra..

I changed the tps..

I wonder if the timing is off some how. IDK how, but that's my gut feeling...

Ideas?

7M's are non-interference engines, so if you're thinking that the sound is valves and pistons making contact, that can't happen with OEM internals.

Nearly forgot i have a code 52.. Sometimes a code 31.. I think until they are cleared up that the car is pulling some timing and that would = the knock knock knock knock..
