Honda water pump
Cap& rotor
Denso Plugs
Injectors (stock)
Fuel rail (stock)
AEM Intake

With all these things replaced I still have a odd idle speed when at a complete stop about 1500 rpm if i hit the gas real qwick it will idle at 900 rpm. still to high i should be 650-750 rpm.

ISSUE 1
When i get on the freeway and boost it reall qwick it will idle really high when i put it in Nuetral @ 4000 RPM and i have to down shift to get it down from that.
Issue 2
I also have a cooling issue as well.
The issue being it will heat up a past way past 210 Degress then i will have to turn on the heat to disipate it. We did a correct 50/50 mix and let it sit to get air out of the lines. Also hiiked a pressure tester to the coolant system it help like a champ @ 17lbs

Issue 3
Air/Fuel
Replaced the O2 Sensor and my gauge says that i am runnig all the way lean doesnt even read at all. When i do start from the morning at a cold start it will go up but only half way sometimes more but a mile down the road it drops Big time all the way so it doesn not read.

I have tried 3 O2 sensors and all the same senario and i know the gauge is right because my car runs like poo with no fuel. There have been a couple and i do mean a couple of times it went all rich and pulled like a scared puppy https://honda-tech.com/forums/images...es/emsmile.gif

So i am at a losing point and cannot think of anything can someone help ? Thanks in advance.

Any suggestions would GREATLY appreciated
