The chirping noise is from the Piggyback. The Version 1 piggy runs off of pressure from the FPR ( Fuel Pressure Regulator ) and it will make strange whistling and chirping noises at idle and under acceleration. Youll get used to it. I miss it when i drive the NSX.

 

That box is indeed the Manifold Differential Pressure Sensor. Don't buy a cheap *** eBay strut brace because the brace will rub on the sensor and break it off. They're not cheap to replace (unless you have about a half dozen of them laying around from various manifold projects )

 

ah , I see thanks for all of the information guys, will let you guys know when he does the pressure test and installs the CEL for me

 

ah , I see thanks for all of the information guys, will let you guys know when he does the pressure test and installs the CEL for me, update the cel and strut bar are finally comming in this wednesday , but unfortuanltay a new problem accured it dies on idels now

 

It dies EVERY time it idles? Wow, that's bad. Sorry to hear that.

 

sometimes it does but not everytime

 

Do you still have the piggyback installed? because if you do it is most likely causing it and you need to raise the idle. It has caused my car to die twice when my idle was lower, I was at a light and the rpms dipped low enough to cause the car to shut off. Hasn't happened again since I raised the idle.

 

Update: Just recived my CEL Elimantor and Strut Bar Today, had them installed boom... IDLE PROBLEM GONE, Lean Problem GONE, Precat Problem GONE..

Only one problem remains.. PO135 O2 Sensor Heater Malcunction
does this mean that I have to buy a new 02 Sensor and then the car is like new .. but with out the aircondiction?

Thanks for everyone that helped me

 

^^^Is that the recall that was last put out?

 

sgt petty, why do you keep posting in threads that have been dead for years?
