Does anyone have a cheaper place to buy Subaru parts? The best I can find on line for the MAP sensor is 181.00 that is crazy for a wiring harness and a couple of vacuum nipples!

So the cel light came on it has 3 codes the MAP sensor the cat system is not working at 100% and the idle air control problems. What do I do first?

A friend in Montana says to always carry a bottle of Heet in the car for Temps under 5 below. He says the water in the fuel lines freeze. He is a master Porsche mechanic and says it has saved his life many many times. Just keep a bottle in the car for the winter.

I hard wired the O2 sensor. I can go back and check my connections. If it was not wired correctly wouldn't the check engine light come on. I can pull and check my spark plugs but, I would think a fouled spark plug would raise the HC numbers and they are low?

Yes mine is a manual 5 speed.

The things that I have read says that a high NOx reading is a lean fuel issue and that vacuum hoses clogged breathers might be the cause. The engine has very few vacuum hoses. Another thing says a clogged EGR valve or system. There is suppose to even be a Nox valve. But before I throw money at what could be or what might be. There has to be a process of elimination.

So the Subaru does not have a EGR valve correct? There are not a lot of vacuum hoses. I did check the seal on the airfilter to make sure that it was properly fitted.

The Cat has a rear port and that is the one I changed!

I have a 1998 Subaru Impreza and I just failed the NOx emissions test. Before the test I replaced the Catalytic Coverter and the O2 sensor, I replaced the air filter and changed the oil and filter.
My Hc was .3655 the Limit is 1.2
My CO was 7.1301 the limit is 15.00
My NOx was 2.4764 and the limit is 1.5
What do I do next? Eric

So you were right about the parts from a junk yard and can buy both for $50(the sensor, and solenoid). I had a bottle of Lucas fuel cleaner and the check engine light went off should I try and get it tested again or should I still assume their is a problem and get the parts?
