Formula 1

ok so thats pretty much it i got 3 codes...knock sensor...vtec oil pressure switch...and fuel metering too lean or too rich...the story wit the car is as follows....00 si wit stock si tranny and jdm gsr long block and IM and headers....i just bought a new harness and i had several codes b4...im running bout .5qts over full on oil. im changin it 2morrow. my guess is the over fill on oil might stop the oil pressure switch from acting up...i pulled the top of the vtec solenoid off and the screen in there was clean...i just put in a new cat(cuz it was clogged...im guessin from blowing the b16 but no oil came out of it so i dunno. im wondering if ne body has more ideas on this. also my headers started turning a chalky color white im guessin from running lean? is this the case or too rich? ne info will be greatly appreciated

does your vtec come on?

Apex i ITR

Using your USDM vtec solenoid I assume??

Formula 1

it sounds like vtec but not but as strong and it doesn't scream the whole time just a lil ways after kickin in.....and its a jdm vtec the whole things is jdm

Formula 1

k now im sure vtec is back cuz i changed the oil and drove the car for a while and the code 22 is gone. i changed the oil....reset the ecu and drove it bout 30 miles...then filled her up wit gas and let myself splurge and hit vtec hardcore and it screamed....then i came home and checked the codes bout 10 mins ago and now we just got Knock Sensor and Fuel too lean or too rich....any suggestions guyz?

I have the same code on my y8/y7 hybrid, i noticed that playing with vtec ground it stop the 22 code.

As for the knock, maybe it is not working but i dont know how to test that? someone?

for the 45 other i really dont know!

Formula 1

well im not really worried bout the 22 code now since it is gone as u might have read in my lat post....but i replaced the knock sensor coupel months ago wit a brand new one...my guess is that the knock sensor is going off cuz if the cr running too lean or too rich...ne body know some simple tests i can do to see how lean or rich it is running and which?...and im thinking lean cuz of the headers turning a chalky white color...ne suggestions guyz?

if your header is turning a chalky white, kind of makes me think you are running really lean.

Pull your plugs and check what color the electrode is. if its white, you are running lean, brownish, is perfect, black is rich.

Did you put new plugs in the car? what gap are you running? new wires?

Formula 1

i have the same thinkin on being chalky i will check the plug 2nite tho.....look at my sig and my car is there shows everything i got ...only thing is that was a b16 i swapped all the b16 stuff over to my b18c when i did the swap i blew the b16. im gonna check the plugs but what if it is running really lean then what? how do i find out y and it is running lean and what to do?
