Got a 92 Si EG hatch with an h22a swap with a p13 ecu and we are having some mind boggling problems...

1) Got it to idle fine
2) When engine is warm, the rpm's surge to 2500
3) Has no power
4) Minor stumble through rpm range (hesitation)
5) 4 CEL's:
1 HEATED OXYGEN SENSOR (HO2S)
10 INTAKE AIR TEMPERATURE (IAT)
14 IDLE AIR CONTROL VALVE (IACV)
23 KNOCK SENSOR (KS)

IACV has been cleaned, coolant is flowing thought the IACV...

Open to all and any help...very very needed

TIA

what model eg? that will help w/ the O2 problem

get another IACV. yours is bad.
Wire the knock sensor
just use a b-series IAT

Model is an SI

O2 sensor came with swap
Can we test the IACV?
Wire the knock sensor? its plugged in...
What will the bseries IAT change?

get a multimeter out and check the continuity between the wires at the sensor and at the ecu. to the knocksenor, IAT, O2 sensor wires. If you have everything plugged in, either a sensor problem or a wiring problem. replace the IACV to see if that fixes your problem. If it does not, its a wiring issue.

Check continuity...all are ok...Dont see this being a wiring problem, since we used the engine harness that came with the swap, and plugged it into our chassis harness for the EG...Can we test the iacv?

if you are getting a check engine light code for O2 sensor, IAT, IACV, Knock

Its one of 2 things. wiring issue or sensor malfunction (replace the sensor)

Ok well its not my car, so i cant tell him to go spend 200 dollars on 4 new sensors to see if it works...any other idea?!

Are you kidding me. You wanted help, you got it. not my problem the person who owns the car doesn't want to fix it.

why do i even bother helping people when they have no intent of even doing anything about it.

HAHA i didnt mean it like that...ill see what we can dig up and ill get back to you...thank you for your help!

iat, iacv, and ks are all the same style plug, do you have them mixed up? let me test myself here without going out and looking. I believe the iacv is blue and blk/yel, ks is a single wire red/blu

sleepin91teg

Chad, weve got diagrams, all sensors and plugs are correctly hooked up...

Bump, still needing help

that was my guess... i had the same symptoms as you and that was the problem in the end... but if your sure there right then i dunno what to telll you other than the sensors bad.
BUT
if its the sensor off of whatever motor you had in there before and it WORKED then its DEFINIETLY a wiring issue... it wont hurt to switch them up and see what happens... (actually it will... if you leave it that way lol ...but who knows, they could already be on wrong) worth a try IMO

let us know whats up
goodluck

DID YOU SKIP THAT STEP???

That will show you if you have the right connector on the correct sensor. And will also tell you if your wiring is correct.

sleepin91teg

The wiring wasnt even connected to the knock sensor...and we tested the iacv, iat and both checked out ok...next is O2 sensor...thanx for all the help guys...keep the help coming
