motor problem help 4.0
I broke my 4.0 ... Its in the shop now.. I was playing with my headlights for too long and ran my batt to low to start, so i hooked it up to a battery jump starter... It didn't work very good so it was just cranking.. I think it flooded... Let it sit over night bc It wouldn't start a half hour later.. battery was charged.. then the next day it started.. but it was... Really rough.. I drove it around for like an hour but everytime I came to a stop I could feel the motor shaking violently and stroking slow and out of order... Almost brings tears to the eye...

I read somewhere that when the battery runs down on these that the engine runs rough and won't idle for a while and I guess 'Magically' works itself out. I just had to recharge my battery due to a bad switch killing the battery, sure enough it was hell getting it started, I had to resort to some old school Carburated tricks of tapping the gas pedal while cranking, it eventually started, but then I had to keep tapping the gas to keep it running.
Anyway after I drove it around for a while, it seemed to work out it's problems and idles fine now.

It was having quite a bit of smoke out the tailpipe and reeked of gas. I'm assiming I flooded it out and damaged something in that process. Or damaged a computer module with the engine start mode on the batt charger? And sound likely?

In my non-expert opinion either one is possible, but I would think if you left the charger in jump mode too long it would harm your battery but shouldn't impact motor operability.
If it flooded and is running rough, I would give it a day or two, but maybe a quick check of the spark plugs may be worthwhile.
