Ok, its a first gen b16 ,intake exhaust. I get a code 2 CEL when I am on the highway for a long time, 2nd o2 sensor. To cheaply get out of this, I just pull the hazard fuse for a while and it goes away. What's probably causing this to happen. The car seems to run just fine. Its only when I'm on the highway for a while.

2nd ?

I am in the process of replaceing my a/c stuff b/c its hot in GA. Anyways, we replaced the compressor with a rebuilt one from http://www.aircoparts.com ($140), the receiver dryer from autozone (a taiwanese part), r134a converter kit from auzne, and the hasport a/c bracket.
the compressor and filter dryer is all in, but my high and low a/c lines weren't both pressurising like they should, so my a/c expansion valve is bad right? Well I bought an expansion valve, but I don't have anything to hold the frion in, so I can put it on. Should I just wait till I have the $ to take it somewhere to let a shop put it in, or how would I go about putting it in myself. I got the glovebox off already and its the left plastic thing under the dash, not the right one right?
Has anyone else had this happen?

 

bump for the ? X 2

 

im in the dark....oh well
