Ok, ran it again at Autozone with their scanner, and they pulled the codes P0170 and P0171. Basically my fuel system was too lean in bank 1 (I think it said bank 1). Car is a mostly stock 98 Civic EX. I say mostly b/c I have an I/H/E combo but thats it.

Where should I start at first? I ended up not replacing the o2 sensor, but I can if thats part of the problem. I've read else where after searching, that it could be the o2 sensor, fuel filter, check fuel pump, fuel feed pipe, fuel pressure regulator, fuel return pipe. Any suggestions as to where I should start first? Any help is greatly apprciated.

 

not sure what would kill the o2 sensor but the one from the dx will work just fine

 

OK cool thanks davefromPA.

Anyone know of any thing that would kill an o2 sensor so quickly? Engines been tuned up with regular oil changes, don't really beat on it, but I did get on it a bit yesterday when I popped the check engine light. Any help is greatly appreciated

 

Bump. New problem.
