1991 SC
Default engine problem. connecting rod? please help

first off let me start with my car. It is a '91 SC with 180,000 miles.
so i was driving and I hit a few small bumps going about 30 mph. I heard something but I don't remember exactly what the noise sounded like, but the noise got me worried.
so I tried a few things while driving and found that I had very little power while accelerating. It felt like I was in 5th the whole time. Also while idling the engine was running VERY rough. shaking A lot, but there was no sound clinking inside the engine.
What could cause this?

REWARD EXCELLENCE!

It would help if you posted this in the S-Series forum, not the SKY forum.

If you lost a conn. rod bearing, you'd be hearing some nasty clunking sounds. I know, I'm just starting to replace an engine for the same thing.

Hitting bumps rarely causes engine problems... but I could see a loose spark plug wire coming undone or possibly a wire getting knocked into the serpentine belt. I'd look the engine over for obvious signs of a failure first.

i dont have a whole lot of info, but id guess lack of fuel or lack of spark. do you have a cel? it should turn on for either one of those. look for a code for a misfire or lean fuel trim or something
