Been viewing/searching the forums here for a few weeks now, Lots of great information Ive found thanks to all you guys
I recently found this car on craigslist for real cheap, needed a few parts, missing body panes, etc.. Someone had also Tried to turbocharge the car, and convert the car to a m/t.
I ended up pulling the hacked turbo kit off, finished the manual swap, got a l1h1 wide band o2, m/t hx ecu, built an adapter to use a ford 2wire IACV and got it running. I've put a good 2k miles on it, not getting that great mileage.
Cars seems to run great, I can see Vtec coming on through my snap-on scanner which im assuming is when the car goes into Lean burn mode? Or is there a few more variables im missing? I've noticed vtec comes on around 3k rpm's and stays till about 5-5.5k, doesnt make much sense. Babying the car around town it would make more sense that it would come on much earlier in the power band and be balanced enough to cover some higher highway rpms.
For the time being trying to see if I could get the car to run right somewhat i replaced a few things with other spare parts off a few other cars from the shop including a viper cat, viper downstream o2 sensor, ford mustang IACV, and i fabbed up an intake out of a spare K&N filter and alum i had at work. Car had some hoodrat exhuast on it when i bought it, i put the cat on the car, and took off the nasty muffler and put on a tad more subtle aftermarket muffler.
I havent seen any codes yet, Ive seen one pending code for some unfamiliar IACV circuit code, but it never set the light or a code.
I've noticed the car will never finish the o2 monitor under the global odb2 diagnostics, just just test not yet complete. If i go under data the Secondary o2 voltage doesn't seem to move through the scanner..... I've doubled and tripled checked the wiring, both sensors are hard wired directly at the ECU/harness, with the original pigtail connectors at the sensors. I've even tried an o2 SIM in place for the 2nd sensor. I couldnt find anyone who would sell me a factory exhaust with the factory cat right after the exhuast ports. so its got an EX factory two piece manifold. I;ve used a viper sensor on another obd1 civic of mine and it worked fine
The mileage i got out of the car to date, is about 330 miles. About half being light city driving, and 15 mins stints on the highway to work and back everyday. Since then its just gone downhill, maybe around 200-250 at the most. Unfortunately the car also has factory civic 15" wheels and tires off an earlier model. I believe and 05 model or so with steel wheels and 7 spoke hubcaps. So I'm not too sure how off my mileage is
Are these cars too picky for me to be tossing parts off other cars on it? Any help is greatly appreciated, im getting fed up with how much gas im spending driving this thing around, its supposed to my getting around FE dd.
