    Hey guys, I have the P1166, P1167 engine light problem on my 2002 CRV. I replaced it with genuine DENSO 234-9005 sensor and I still get the same error. If I clear the error with my OBD reader, all I have to do is turn the engine on and it comes up after about 10 seconds. Is it supposed to...

    Maintenance and Service
    2003 CRV with 127,000+ miles. I intend to keep this car as long as I can as I did with its predecessor, my Civic Wagon. Are we at the point where I should consider putting in less expensive replacement parts? Dealership service dept wants $424 for rear brake pads & rotors, $318 for the...
  6. 01 backfire, but no check engine

    Problems & Issues
    Hi, I have an 01 honda crv and it makes a "popping" sound when the engine is warm enough. It has no power when driving on the freeway or sidestreet. It makes the popping sound worst when I hit on gas. The only way I can go 65mph on the freeway is to go O/D. Changed the Catalytic last month...

  8. Cat Converter... Or is it?

    Problems & Issues
    Hey all, I have a 2001 LX 4wd w/ 175k on it. Over the last year or so, I've had the engine light coming on and off intermittently. It was showing the P0420 code. It ran fine until about a month ago when it started sputtering under load (I.e. accelerating, A/C, etc.). My assumption was that...
