aight, so heres the deal, one night im out and me and my friend with a MS6 and my other frined with a civic si are playin around. car was boostin fine at 14-15 psi no problems. AFR is sittin around 11.5-11.7. well the next day or so later my car all of sudden starts runnin rich and im talkin 10.0. and i only hit like 8-9 psi before it starts sputtering at WOT. i talked to vince and he said im gettin knock and the ECM is pulling timing (which as been there since the beginning due to my solid trans mounts). so i take out my trans mounts and make sure my manifold and turbo is tight, still not the problem. i replaced my MAF and got a new knock sensor, still no. a friend of mine comes by and inspects the car by spraying starting fluid around my IC piping and and intake manifold, engine doesnt pick up. then he sprays it at the injectors and one of the injectors sucks in the fluid which tells us i got a vacuum leak but instead of the engine pickin up it starts dying out. so that meant 1 of 2 things either the plug isnt burning all the fuel or the injector is stickin open. i replaced the plugs and still didnt help so i sent my injectors in to get repaired and my injectors were perfect before i sent them in and came out with the same results upon being shipped back to me.

if anyone has any clue what might have happened or has any suggestion please tell me asap. i got new o-rings for my fuel injector boots so hopefully that fixes that vacuum leak but still doesnt explain all the fuel. WHY THE HELL AM I GETTIN KNOCK?!?!?!

my engine specs

- GT3076R turbo
- 60# injectors
- 2.2L stock motor with forged internals
- 50/50 meth
- trifecta tuned

sorry for the long post, i just wanted to let everyone know everything i know at this point, thanks for the help everyone

Is your meth stuck on all the time by chance?

You may be getting knock due to it being rich as well

i dont think so. i ran it one time with it unhooked and still had the same problem. the injectors come tomorrow so im goin to ran some more diagnostics if i get more suggestions

plugs looked alright but i can take a pic of them and post them up if you want to see for yourself. but i bought some 2 step colder plugs and it still didnt fix the problem

UPDATE:

got the injectors back from injector-rehab.com and the injectors were perfect. so i placed then in the boots and head and made sure there was no vacuum leak again like when my friend found one, hooked my knock sensor but ima hook it back up to test it again. i just got back from takin the car on the highway, hit 14.2 psi with ease, no sputtering or anything but still ran a mid to low 10 AFR, so im guessing just a little retuning and itll be fine
