I gutted my precats, and afterwards noticed that the charging system light was coming on at about 4000 rpm, and the car didn't seem to be running terribly well. I took it home (the precats were done at a friends house) and noticed that it seemed to not be in good spirits, and the lights were flickering quite a bit (I had already had suspicions that my alternator was dead/dying).

At home, I decided to put it in idle and rev it a bit and turn on and off stuff and see what happens. After noticing that every time I put a load on the electrical system, the revs seemed to drop. I put it in diag. mode to view the rpms, and sure nuff, it was doing as I suspected.

Then I decided to turn on everything I possibly could, and the rpms dropped very low. Then I started rolling the window up and down to add even more low, and the revs sputtered and stalled. (a hearty w00t to Ford's electrical engineers . . .

)

I tried to restart my car, and I was rewarded with cranking but no firing, except the occasional popping sound, and the slight smell of gas (which means the fuel pump is fine, I think)

Over the last week or so (I haven't had much time to work on my car) I tried hooking it up to a running (and working) car to charge the battery and start it, to no avail. A friend of mine offered that during my (stupid) loading test, there was not enough power to make a spark, stalling the car, and the successive cranking flooded the engine and soaked the spark plugs with gas. Sure enough, after taking the spark plugs out and cleaning them (well, wiping them off, I didn't have anything good to clean them with), cranking the motor a few times with no plugs in (my friend's suggestion), and reinstalling them, the motor actually started and ran for a good ten seconds before stalling again.

So, any ideas.

EDIT: Oh yeah, also, I had a CEL, but my friends scanner told me that it was the number two O2 sensors in each bank which, I believe, just means that I screwed up with the MIL eliminators.

more editing: I just went out to try to see if my car would start, and now it is not even cranking, just clicking. My passenger side window has been completely unresponsive since before doing the precats. Along with the other electrical gremlins, could this mean there is a short in the system, or I have a bad battery?

Nothing else matters, not school, not sleep, not my bank account. But for those ten seconds or less, when everything works right, I'm free. Last edited by frinesi2; 05-29-2008 at 12:06 PM.
