Heres my question. This is for a 95 gsr.

I know my O2 sensor is bad which is making my car run rich and is prolly messing up my cat, which in turn is killing my gas mileage. I was thinking that maybe a fuel pressure regulator and/or fuel rail would help the car run leaner. So should I get a new O2 sensor or would a fuel pressure regulator and/or fuel rail help my car run leaner and help my gas mileage?

 

well if ur 02 is bad then y wouldnt u replace that first??

 

havnt really heard of any1 getting a FPR and a Fuel rail just so they can lean out their stock car

 

I just figured to save some money because I was eventually gonna get a FPR and fuel rail in the near future.

 

so get em n get an 02 its not like it cost 300 for a 02

lol i just replied to this question in the other honda forum hehe..=P

anyways like i said, replace the o2 if you think it's bad..

 

dont mean to jack the thread sorry im a noob but where can i purchase one and how much is a o2 sensor

 

lol like any autoparts store depends on what brand you get

 

you can usually pickup a univeral 4 wire o2 for about 100$ or less. make sure you replace that. A fuel pressure reg. wont do much. THe ECU will keep trying to compensate, reverting your lower fuel pressure adjustment.

 

Try http://www.oxygensensors.com

They sell OEM style o2 sensors at decent prices. They have a Walker OEM for about $125 and a Denso OEM style for about $190. If you don't want to spend that much money, just get a universal one at any auto store. You'll have to do the wiring yourself and I've also read that people have had problems with them.

 

thanxs.

 

I think Im just gonna get a new O2 sensor. Gonna try to find a cheaper priced sensor than the ones on oxygensensors.com

 

my friend at acura said it was 85 bucks installed? dunno..

 

can someone confirm the price at acura for install and parts?

 

or you can try a vafc and trim the fuel, not sure if it would work though for your porblem
