New member, California, 1997 civic HX
 

Greetings Ecomodder community. Came across your forum while googleing for tech info. I'm coming from a 2006 accord 4cyl 5mt which would pull around 40mpg on highway trips by keeping RPMS to 2300ish (55mph), or 25mpg when driven angry. Made a change recently and am now the proud owner of a 1997 civic HX. I've been drooling over Honda Hx / VX models since I first heard about their lean-burn tech (~15 years ago). So now that these cars have depreciated into nothingness I jumped on the opportunity to pick up a good runner with some issues for under a grand. Looking forward to sharing my experiences.

Welcome! And good luck with your "new" HX.

Forgot to mention, If anyone is tackling a modification/repair and needs a wiring diagram or the like PM me.

Welcome! What kind of issues does the car have?

A few cosmetic issues, some title/reg. hoops to jump through, also gotta pull the cluster and make sure the check engine bulb is actually in there and plugged in (no CEL w/KOEO). No codes, fingers crossed that it passes sniffer test. Car runs great aside for a bit of synchro grind on the 2-3 upshift, gonna put some friction modified trans fluid this weekend and see if it mellows out.

I have the 3rd gear synchro grind too. Been that way since the transmission swap. I think I put a heavier oil in, IIRC. Problem did not go away completely. But as long as Ishift mellow style and don't race/cram it, it is symptomless really. I am testing a CAT cleaning method. I'll know soon if it worked to improve my CAT i hope.

Let me know how the cat cleaning goes. I saw something like that mentioned on "eric the car guy" and will probably go that route if neccessary.

If you need to shift at high RPM double clutch and it wont grind
