Hey all. I just got done replacing both O2 sensors on my 05 WRX STI. It was throwing a running rich code, and getting abysmal fuel mileage, hence the sensor replacement. Now after the sensor swap, it hasn't thrown the rich mixture code with a 5 mile test drive. Now however it has a wandering idle.... -
Hello: I have a 1995 Subaru Legacy Wagon. EJ22 / 186K. As it has gotten colder car has a fuel smell @ start up. The fuel smell is coming from the tail pipe and it seems that the car is running rich until it warms up. It has not thrown any codes. I am thinking that the O2 sensors nee... -
I have a 91 Subaru Legacy and it will not stay started when I start it unless it has been sitting for awhile, for example overnight. But if for instance I drive to the store and then shut off the engine and go inside and then come back out and try to start it again, then it will not stay started whe... -
Hey Y'All, My '91 Subaru Legacy seems to have a flat spot (I believe that's the correct term, but I'm still not fully versed on some of this stuff). Generally occurs when accelerating (usually somewhere between 2k and 3k RPMS) or climbing a hill: I'll depress the accelerator but nothing happens... -
I have a 2005 outback llbean 3.0 with 146,000 miles. Today the check engine light came on with a blinking cruise control light. Had the code pulled at Advance which said P0420 Catalyst system efficiency below threshold What is the fix? O2 sensors? up or down stream is there a way to determin... -
So using an obd tool i got the code p0051 for my 2004 Legacy (35th Anniversary Edition) and subsequently changed the bank 2 O2 sensor 1. I am now getting a p0151 code which is low voltage for that brand new sensor. Strangely enough, in trying numerous possible solutions (cleaning the mass air filter... -
I have a 2003 Subaru Impreza Outback Sport with 73,xxx on it. Recently, it has started to hesitate badly while accelerating and will not go faster than 50 mph. I took it to the local dealer, who wants to charge $2,300 to replace the catalytic converter and front o2 sensor, saying it was plugged... -
I received the following 2 codes late last year: P0030 Heated oxygen sensor heater control circuit Bank 1 Sensor 1 & P0134 Oxygen sensor circuit no activity detected Bank 1 Sensor 1 After resetting the codes about 2 or 3 times, I replaced my Upstream O2 Sensor. No issues until jus... -
The title pretty much explains it. Hubby replaced the battery today and the o2 sensor (based on a code 51 reading). He then tried to reset the code with the engine running and found out that he wasn't supposed to do that. I don't know if that is the problem, but now the car will not start. I... -
Ok so...the light is on on the dash. The car RUNS just fine. If I do not have to pass any inspections, is there any reason to go thru the hassle of changing my O2 sensor? I have a new Bosch and hear they are not the best anyhow. I will have more questions later as there are some tubes at the car...

So my legacy should be getting around 20 mpg city but is only getting about 15. It also has the slight smell of gas when you start it first thing in the morning but that goes away after you start driving. I looked around and the most likely suggestion was a bad o2 sensor. What do you all think of th... -
Hi Everyone!! I'm in need of some help. I live in California and I bought a 07 Impreza 2.5i (non turbo) about 2 years ago. After my first smog check the car's check engine and cruise control light came on. The cars performance has not changed or the gas mileage so I didn't pay attention to it. N... -
I have had no problems driving the car. Parked it in the garage last Friday. Monday morning, it won't start but it does turn over and cranks. I have checked the following things: -- spark, good in #1 cyl. Didn't check the rest -- fuel, appears to be getting fuel, didn't measure fuel pressure... -
Hi, just joined. I have a 97 legacy outback limited. Just replaced the O2 sensor and the Knock sensor per codes that came up on the diagnostic check. Check engine light stayed off for about 2-3 weeks and came back on a couple of days ago. Ran another code check and the only one that came up was P014...
