So i have an 89 wagon just put built ls/v turbo in and i FINALLY got it to run ( if you were following my other threads) I have a p28 chipped on chrome. The car only will start if i feather the throttle, it will not idle on its own and it will not rev past 3000rpm. Ive checked the codes and they are IAT, and Water temp (6 and 10) im running an Aeromotive 340 intake pump, and dsm 450's. I dont have the ic piping hooked up yet im just trying to get it to run correctly. Any ideas on the idle/rev issue? The IM i have doesnt have the place for the IAT so im just gona have my buddy dissable the IAT sensor next time im in town but that wouldnt make it run like this i wouldnt think? Any help would be appreciated!

 

Don't disable the iat. The car needs that to run properly.
If your manifold has no place for it, then attach the sensor to the IC piping.
I've read best place is to put it right after the IC pipe.
Water temp sensor is what makes the car idle correctly in the first place because its in a closed loop when you first start it.
Fix those cel then see what happens.

 

On it thx ill keep you updated

 

What was wrong the first time u never updated the other thread

 

Sorry man! Two of the original yellow wires for the dpfi injectors I actually cut needed to be hooked up to b1 on the Ecu side because they still ran to the main relay! I started it up again and kept it running for a sec and it now has codes 6,7,10, and 14.. i know for sure now that I have the wrong connector for the iacv hooked up so that's why it's throwing that code. But idk why the tps is throwing a code, I swapped the two outer wires like your supposed to and I know it's not mixed up with the map sensor plug because the map sensor plug was attached to the fire wall and still is while the tps is actually built into the engine harness. And idk why the water temp is throwing a code either

 

Did u ever use a multimeter to check continuity from ecu to connectors???? It would solve alot of headaches

 

that is what im about to do next!

 

Yea thats what u should have done to the harness before u even hooked it up to the engine

 

man, mixing those tps and map connectors is a pita lol.
but I think the tps has a solid red wire, but you got that figured out,
alos, if you hve an evap solenoid, the connectors for the evap and iav are exactly the same, I mixed mie up and didn't know what was what till I saw a wiring diagram, good luck.

 

also, take the water temp sensor out and clean it, that may be why its throwing a code,

 

I took the engine harness out and basically rebuilt it/lengthened/and put better connectors on. I've got it running finally! I still have the tps, cts, and iat codes but it runs pretty good! Haven't got to drive it yet to see how it runs under load but soon I will.

 

sweet
you say you built the lsv.
as in built do you mean new rings and cylinder honing?
if so, idk if the iat cel will affect the seating of the rings.

ive had tps cel before, the throttle wont respond as needed while driving.
also with cts itll always run in closed loop mode

 

Tps, ect, and iat share the same ground that goes to d22. D15 is iat. D13 is ect
D11 is tps and should be the middle wire on the connector d20 is also tps double check those with a dmm

 

wow, when I did lsv all these sensors failed on me too at once.
would the 95 integra ls have the same ground? D22?

 

Yea the same...o2 ground is also d22 damn u guys dont look at wiring diagrams or wut??

 

Ok so I got the tps and coolant temp codes to go away thanks to jdmjunkieXL they were not grounded at d22! Thanks bud that's the first thing i checked. But now for some reason it just started throwing the cyp code 9! If its not one thing its another! I don't know if its just an intermittent thing or what, because it never threw it before.

 

I think mine was a coincidence cuz I replaced the tps and iat sensor and the ect. and the codes went away

 

I had this code, was intermittent, started off by cleaning the cap and rotor, cel went awayfor a bit then came back, ended up having to replace the distributor.

B11 orange and b12 white are cyp check those from ecu to dizzy

 

I've checked them and went through the test that it tells me to in the link above that jdmswagserf posted and everything turned out good.. It's spitting and sputtering and doesn't have any power

 

no other codes besides #9 right?

 

i have code 9 and 10 the iat sensor but thats on because i dont have it installed yet. just wouldnt think that would cause it to run this terrible

 

so would the #9 code make it run absolutly terrible? bad idle, spit and sputter, etc?

 

so i took of the dizzy today and one of the tabs was broke off. would that cause the CYP code to come on and make it act all crazy?

 

that would probably make it run the way it is because the teeth go in a certain way.
replace those teeth, just pop the snap ring off and put a different set on.
if you have the iat sensor, I would just plug it into the harness at least.
