Code 45....Need Help Please!....Long

[speedy108]

Well let me tell you the story that brought this about.

Installed my clutch two days ago and pluged our Snap-On Diagnostics computer in and was looking at what my timing was set at. Well I was going through everything and saw that my Idle Air Temp. sensor was reading 385 Degrees warmed up at idle. WOW. well we found that there was a short in the wires going to the sensor so we just wired the sensor in directly to the harness. FIXED!

Now it read 107 degrees at idle. The weird thing is that all the time that those wires where shorted out, it never threw a CEL. Ok!
So we got everyhting done and I drove home that night and threw code 45 the next morning, which is too lean or rich mixture.
So I reset the ECU and drove it again and the next day (today) it threw that code again and could tell I was running really rich. I could smell it inside my car.

Now my question is:
Is it possible that when I tuned the car when I didn't know those wires where shorted out, that my car needed so much fuel that now it's fixed it's throwing that code because I'm way rich?

My Max fuel pressure is at 95psi!

Here is my setup:
'99 Integra GSR
Jackson @ 9psi (Jim's pulley)
Jackson Map Mod
Jackson Water Injection
Intake
DC 4-1 JDM Header
Testpipe
Thermal "3 Exhaust
Fuel pump
Cartech 2025
Prelude 290cc Injectors

Please help if you can. Ihate check engine lights and my car runs like it did when the short was in the wires.

Sorry for the long post. Any suggestions are helpful!. If someone has a similar setup as mine, could you please give me your fuel pressure settings on the Cartech,fuel Press. regulator and Max fuel press.

Thanks, Michael

Anyone?

Definitely could be because of tuning while it was shorted. The ECU gives more fuel the colder it gets, so you might just have to richen things up somehow.

That's the thing, I think I'm too rich because I can smell gas and it bogs a little when I give it throttle at low end. My A/F gauge is in like the fourth from the last green. My fuel pressures are really high too.

Can someone please give me fuel settings that they are running right now?
Read my post above for the setup I'm running.
I need Max Fuel Press., Static on Cartech, and Static on the AEM FPR.

Can anyone give me some fuel settings I need?

Your static pressure should be around 40 psi, and you should max out around 78-82 psi at 9 pounds of boost.
Have you actually monitored the IAT to make sure that it is functioning ??? I have seen very high temps as you have described on cars before... and when I pulled the IAT sensor from the manifold, it looked like someone had burned the end of it... and it did not function.

Have you made any other changes ???

[speedy108]

Replaced the sensor that was in the manifold after we found the short. It was burned on the tip to the point that it looked useless. I replaced the sensor with one that was in much better condition and did the rewiring to the harness. I checked the temp on the sensor and it was fine after we got done with rewiring. I checked it the next day when I threw code 45 and it was fine.

When we pulled the code on the diagnostics test, it read that it was lean. Weather it ment it was the lean/rich code I don't know, It just said:
Systen Too Lean.

Now my question still stands on why it is throwing this code now and not before when the wires where shorted out. I have changed nothing but the clutch and rewired the IAT wires to the harness.

Please Help!

I get that stupid code all the friggin time, at idle nontheless. [img]confused.gif[/img] I'm about ready to disconnect the SOB light. Can anyone tell me which wire it is coming from the ECU? I've got a pair of wire cutters handy [img]smile.gif[/img]

I hate to tell you, but cutting the CEL wires is not the correct way to fix the problem. Try to borrow a scantool and monitor the Short & Long Term Fuel Trim to find out if your car is running lean or rich. Then you have the information to make the proper adjustment. It's not that hard...

I know it's not the right way. But the car was running fine and never threw a code 45 CEL until I installed my catchcan correctly... go figure. Nothing else has changed.
