well after a good amount of money to honda lol for some work and a good bill of health i get told the fuel is due to the lowering kit who ever had it before me put on it its so low that its causing the back to drag threw off the alignment which i found out on the freeway on the ride home from the dealer so time to save up and look for some used springs to save a little .i’ll keep every one posted
Wow, thanks for posting the fix. Was the car this bad on fuel when you bought it? Good luck man, and mark the stoplight green before Dreamer and his stoplight nazis come for you 🙂
Yes, very interesting about what the real issue was with your gas mileage. You might try this link for some used springs. They are located in North Carolina so it might not be worth your while as far as shipping costs even if they have the parts. Just a suggestion…
http://www.beavershondasalvage.com/I’m a little confused by this but a car that has been lowered might have other modifications as well which could effect fuel mileage (like a reprogrammed ECU) OR it could be an indication of how the car was maintained, meaning it could have been abused which can wear out parts prematurely causing a drop in fuel economy. I also can’t stress enough how important good tires are to fuel economy as that effects rolling resistance, cheep tires =cheep results. Keep us posted.
^Maybe the lowering efforts previously somehow adversely effected the fuel economy relative to the aerodynamics? Great tips on tires and keeping them inflated, generally 1 PSI per 10 degrees, so I check my tires once a month or after drastic temperature changes.
thats what honda has told me i purchased 4 used off a 2007 63k miles i plan on putting on thats what i was thinking eric was the fools did some thing stupid all the engine mounts are new im surprised for only 109 k buy honda said it all checked out well as far as fuel trim etc and sorry i thought i marked it i guess i did it wrong lol thanks again every one
oh and yes i noticed about a month in that the fuel was horrible so a few more fixes new tires etc etc and hope all is well
^You know that hit me as well, but it could’ve been a bad lowering job. lol
Anyway, I think the ideas of seeing what the fuel trims are like currently might reveal a bit. Could be a lazy sensor but wouldn’t surprise if it was a performance tuned ECU.

Actually that might improve aerodynamics, think LeMans race cars.
That said I suspect you’re dealing with the ‘modifications’ of someone else and to be honest the only way to really know what’s happening in there is to take a look at the live data and fuel trims to see where things are, they may have installed a new ECU to run a different fuel map for performance purposes.
It’s not likely to be a lazy sensor if the PCM is working properly, if that was the case it would set a code as the later model systems are very good at picking up a lazy O2 but the fuel trims will tell the story I think.
^Ah, right on. That makes total sense as older system like on my car have to basically have a dead sensor before a code is set, especially with the age on this older tech.
thanks you guys again for all the info and help they did a drive fuel trim test i forget the real name and they where on the money when i had it in to honda and after the work honda did they said the engine is healthy so now that its lifted i hope it fixes it or at least helps .i’ll keep you guys posted http://www.flickr.com/photos/74287903@N02/6986543319/in/photostream/ before and after http://www.flickr.com/photos/74287903@N02/6986543645/in/photostream/
well i ended up buying a used service manual and an going to try and find out if i can reset the pcm my self because im a a loss honda says the fuel trim is normal nothing with the engine ,cars lifted to normal i mean the only think i can think is that v6 hates me because i only maybe put 6 miles a day on it lolor honda’s lying hoping i’ll break some thing and there get to fix it which i dont believe . one question i do have is do the scan tools actually know if the o2 sensor are really working or is it a quick test it runs ?maybe a clogged cat car does stink if i lay on it hard for a while .some day maybe i need to swap it to a 5 spd turbo diesel engine there i’ll get the good mpg.
