Car Forum / Honda Cars / February 20071997 Honda CRV Check engine light
I have a 1997 CRV and check engine light goes on and off. Have checked all fluids - gas cap etc - everything ok. One thing I notice is that when the light comes on, the engine appears to idle not at a steady rate - revs go up and down - and you can see it on the Tach needle. Am wondering if it needs new fuel filter - would appreciate any suggestions mountainridge@netscape.ca wrote in news:1170540278.730764.140750 @q2g2000cwa.googlegroups.com: > I have a 1997 CRV and check engine light goes on and off.

AutoZone, PartSource and many other places will read the code for free. Report that code here. Fluctuating idle can be anything from low coolant to a big air leak. Check your radiator's fluid level (when cold!).  SignatureTegger The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ > I have a 1997 CRV and check engine light goes on and off.

Get the code read at PartSource, and meantime, see that the coolant is full in the rad and full to the MAX mark of the reservoir. Air in the system of a '97 will cause the idle to go up and down. You should book yourself a valve adjustment too, and request they set it to the loose side of the specs. The owner's manual is incorrect about the interval. 'Curly' Many thanks for the prompt reply - unfortunately went ahead and changed the fuel filter and you are right. Am going to check rad coolant as you suggested - also book a valve adjustment job as it has 206,000KM (130,000 miles)- on it with no valve slop. An interesting side note to the fluctuating idle speed of 900 - 1600 rpm's on the Tach is that as soon as the vehicle is put in drive - the fluctuations end and it even's out at a steady 900 rpm's Mary > mountainri...@netscape.ca wrote: > > I have a 1997 CRV and check engine light goes on and off.

HAVE THE CODES READ FROM THE COMPUTER. It will tell you what area to look at. AutoZone and other parts stores will read them for free. Bad fuel filters show up at higher speeds, not idle. They start restricting fuel flow at the higher end. > Many thanks for the prompt reply - unfortunately went ahead and > changed the fuel filter and you are right.
