Got Code 52: Knock Sensor... Options

[gtfc115]

Ok so just recently ive been getting a CEL and the car has been hesitating under full boost at ~4k rpm. it also stumbles pretty often when it's just idleing.

the most recent changes ive made are my new 3" exhaust, raised boost to 13psi (for 1 day), gapped my plugs down to .028, and capped my turbo pressure sensor (to get rid of fuel cut and raise the boost.)

now i get this code 52 and pretty bad overall performance...it was running so well, so something i did messed it up.

well, there are TONS of reasons it could knock...bad gas, too much boost, detonation, ect ect..
once you get the car up high enough, its just a matter of snaking your arm up there and getting to it.
its not hard at all, just a matter of getting in the right position to get at it.
have you checked your timing with a paper clip or whatever in te1 and e1 ?

no i havent checked the timing...i'll go buy a timing light in the next couple days. luckily i have my work truck i can drive till i get this fixed. i just wish it was turbo.

Appreciate the help guys. Thanks!
