Sputtering, stalling, lean conditions
 

Read thoroughly please, I have checked a lot myself, I'm a mechanic but I dont have diagnostic tools. So my car started to kinda hesitate a couple weeks ago when I'd pull off from a dead stop. Then the next week it started misfiring when I would pull off from a dead stop then at low throttle inputs it would completely shut down injectors and would barely pull itself, my wideband reading ---- which is off the charts lean. I checked my VAFC harness for problems and found nothing, I even removed it and the car was still acting all crazy. I ended up unplugging the primary O2 and then the car ran fine, like normal actually, but it was idling at 1500-2000 rpms which is rediculously annoying with my stupid loud exhaust. I got an O2 from Billman and plugged it in and reset the ECU. The same problem comes back. It actually seems to have gotten worse, stalled a couple times when I tried to take off, just barely giving it throttle. My wideband is reading 15:1+ a/f ratios under full throttle which is piston melting a/f so I really need some advice. There is no CEL. Any suggestions? This is pissin me off, the dragon is next weekend!

i would sure like to know as well...please keep us tuned in.

Downloading manual from hondahookup as we speak.

have you tried disconnecting the battery overnight?

No, but I dont think thats necessary, unless there's something I don't know about. I had a code from where I disconnected my O2 so I could drive it home then disconnected it for like 20 mins and the code was gone.

Do you have a cat or a test-pipe?

If you still have a cat, try unbolting it and taking the car for a spin. See how the car drives then.

I have a full exhuast with test pipe arriving wednesday. However I found that if I floor it and release the pedal slowly I have a flat spot in the pedal, going to find a scanner and see if I can read the voltage outputs. would the TPS cause this kind of running condition? Very strange... still diagnosing, frustrating!

What you guys think about the map sensnor?

Have you tried a map whack? Search the forum for it and try it.

I had this slugish before from a dead stop and trying to move again.

Might be very bad heat soak or just try a map whack.

GL, keep us updated.
