I have been battling a knock issue with my car since I bought it last march. I just did another log and found something odd(at least in my opinion), although Im not sure if the injp is worth anything on the logger, but here is the deal. At 99.7 tps my injd is only at 73.4% and never went past 87%. Do you think my injectors might be causing the knock? o2 reading was at .87v. The car is basically stock with the exception of an evo turbo, and k&n filter. Here is what I have tried to cure the knock.
New walbro 190 (the car is an automatic)
Gen 3 lifters
New mitsu knock sensor
New mitsu 02 sensor
New timing, and all components associated with, all oe mitsu
New fuel filter
New fuel regulator
Fuel pressure gauge shows pressure is fine
About the only thing left of which I have read about are injectors and CAS. I had the timing belt done at DSMotorsports so the it was done right, and the timing has been checked many times.
Oh and one last thing, the car does not knock every time, but it mostly does it when at off idle acceleration. Immediate knock count of 43.
1993 Mitsubishi GSX Automatic
