Hey all- Just recently finished swapping an h22 into my 92 Si.

Starting the car up and running all works fine with no CELs..

Normal driving constitutes no CELs either..

However, when i'm up in the revs at about 7000rpm i get a CEL and it stays on until I turn off the car. Without having checked the code yet, what am i to expect with this?

edit:: ps. P28 ECU.

 

If I were to guess, I would say o2 or bad ground on the vtec pressure switch. you should be able to pull the code though.

 

yep i'm gonna pull it tonight, i just didn't want to last night.

thank you.
