Apparently I've been boasting too much lately how trouble-free my Fireflies have been, and the universe took note. The Blackfly took ill suddenly today, and I'm out of ideas on what could be wrong.
Here's what happened: was out getting supplies for the tranny swap. On the way home, after bump-starting the car at one point, it started as usual, but running really roughly. So I quit codfishing and just pointed for home. Mileage on the SG plummeted to 25 by the time I got in the driveway.
Black sooty smoke is coming from the tailpipe, even at idle, and it smells to me like it's rich (duh).
The CEL is not on.
There was one code stored in the computer, which may or may not be related to the problem, but I'll say it anyway: it's for the camshaft position sensor, AKA the distributor pickup coil. My kill-switch is wired in this circuit, and I have mistakenly generated this code before by trying to start the car with the switch in the wrong (off) position. I did make this mistake on my previous drive, so that's probably where the code came from.
I removed my switch from the circuit and also swapped a known-to-be-working sensor over from the ForkenSwift. No go. The car runs the same.
I reset the error code and it hasn't come back. No other codes are coming up, and the CEL is off, which is really surprising considering how crappy the car is running.
Spark plugs are black as night, covered with soot.
Battery voltage is fine (I re-connected the alternator).
I'm not rly sure about jumped teeth, but it's often said it will prevent a honda from starting if it's bad enough and if your timing is way off it's quite concievable you'd be ejecting unburnt gasoline. And jumped timing is just something that happens randomly, which is why I thought of it.
Don't know if this will help but saw the post and googled the black smoke from tail pipe and found this: It's for an Explorer but might be worth looking at.
Most likely you've got a blown fuel pressure regulator, which is pushing
fuel directly into the intake via the vacuum hoses that connect on the
drivers side toward the rear of the motor on the side of the upper intake
manifold. To test this, on a COLD ENGINE remove the two 'hard' plastic
lines from the vacuum tree (they'll have rubberized right-angle nubs) and
get someone to flip the car off to on for about 3 seconds, you should hear
the fuel pump run. If gas comes out of either of the hoses, you need a fuel
pressure regulator (only one of those hoses is the fuel pressure regulator,
its just too bothersome to trace the lines, just yank em both)
Also found where the said could be a clogged injector?
Just trying to help but I'll leave to you guy that know alot more than I ever will. Good Luck.
