i think i messed up my ecu due to me running no o2 sensor for a while and also not running a knock sensor.

i believe the ecu is used to running bad, cuase now that i replace the knock sensor the motor continues to not hit vtec, continues to misfire and stumble and also the motor surges inbetween 1k and 2k.
what should i do???

 

You cant hurt the ecu by not running an o2 or knock sensor. If you replace those and you still have problems then you have other issues. wiring, distributor, fuel. Start with the basics and go from there.

 

might even be my timing,

 

I have a bad wire harness
all my sensors are like half connected and all shot n poopy.
i need a new crx Sir B16a wire harness not spliced, one thats mad for the car and the swap..

 

just get a hold of a harness from an si civic or crx and add in the wiring for vtec, the second o2 sensor, and your knock sensor.

 

got a civic si harness
the problem was my temp sensor and my main ecu plug i forget what its called. its underneath the distributor. car starts and runs now but now its throwing code 9 and code 3 which is the dizzy and mani obsolute pressure. idk if thats a vacuum leak or what but.. all i know is it sucks not having vtec. lol

any one know whats good with codes 9 ,3

btw my spark plug wires are beat and so are my spark plugs.
ill see what happends after i do a full tune up
